Why I’ve left MTN

So I’ve been shopping around in a non-serious fashion in the last few months trying to figure out how best to leave MTN and how get the best deal for me. I don’t like MTN since I became anirate“, as I might call such a customer in the ISP industry. MTN’s Customer-Service Call Centre had rarely been helpful or knowledgeable on their own systems. The final straw however was when their systems let me screw myself over and Customer Service was as helpful as a dead redshirt:

I had a billing issue where, admittedly, it started of my own fault. MTN has a feature where you can call in to find out the amount owing on your account. Only, as Murphy would have it, this amount was the amount owing on the account but the last amount that was billed.

So one month my account was about R900. I called the number, mis-heard R500, paid the amount I thought I should: R500. 15 days later MTN suspended my account. No wrong done, right? Wrong.

First off, I received no notification of any kind. An sms would make the most sense, especially since it would cost MTN almost no resources: “Your account xyz is in arrears by R400. Please contact blah blah blah”. They could phone me, they could email me, something, but nothing of the sort happened. Suspend without Prejudice. Thats the best way to get the customer’s attention!

Now, not only could I not make calls and sms’s, I could not receive calls or sms’s. Further, I could not even call MTN’s toll free phone number. I had to use someone else’s phone to get to the bottom of the problem. After two days of haggling I finally found a lady kind enough to re-enable the account. Ten days later my salary goes in, I call the same number and hear a number close toR900”. I think to myself maybe I should double-check juuuust in case I mis-heard. I call again, I hear the same number again. Right. Pay the R900. Fifteen days later, my phone is suspended AGAIN. WTH?

Remember what I mentioned earlier?: “this amount was the amount owing on the account but the last amount that was billed.” So, in spite of the fact that the voice prompt specifically saysPress 3 for Balance Due; [Presses 3] ; The Total Outstanding Balance is; Nine; hundred; 和; #whatever ; Rands; 和; #whatever; cents”, I actually owed them R900 plus the R400 that I’d paid short the previous month. 不, I do not know if MTN has fixed this. I no longer care. Since I figured this out I started waiting for paper statements to see how much was actually due. Interestingly, their paper statements were also wrong. Only they had the opposite problem: “This invoice: R1300in spite of the fact that on the next page it says opening balanceR400”, closing balanceR1300”. Pah! Is it fixed? 再次, I don’t care.

I let them know I wasn’t renewing the contract and I’ve now already ported my number away to Virgin Mobile. Because I want to keep my number and port it elsewhere, the store said I could not putunsatisfactory serviceas the reason for ending the contract but that it should simply sayporting”. Apparently by putting anything else there they might notnoticethat I want it ported. WTF.

What next? (without MTN)

In my research I’ve found that contractdealsare most popular. Typically, you can get a R8000 phone for R800 per month over 24 months with R500-odd worth of airtime per month. This amounts to you paying R19 200 over a 24-month period for a phone worth R8000 which will be obsolete within 12 个月. You will get some airtime every month so you might feel its not a complete loss. However you should also remember that it costs the cellular companies nothing when you make those phone calls. 利润.

There’s a better way

There are much cheaper contracts, contracts for between R50 and R200 which include cheapish phonesphones that work damned well as a phone but won’t let you play games on the train. Most of these contracts actually give you the same airtime value (sometimes more!) as what you are paying. So for R100 you might get R100 worth of airtime plus some free sms’s, and a cheapish phone. The best deals I’ve seen recently have all been for the Samsung STAR, an understated but good cell phone, available from a number of retailers for between R100 and R200 per month. In most cases the deals have included the full amount of airtime. Virgin Mobile has probably the best example here: The cost is R199 per month which includes R200 in airtime and 1000 sms’s (是的, you read that rightone thousand!).

Virginal Service All the Way!

Another reason I’ve gone with Virgin Mobile is a little something no other service provider does: AmixedContract/Prepaid facility. I get R200 in airtime however, if I go over that, the extra just gets added to my invoice. With MTN this could go sky high without the option of a limit! With Virgin, because I asked, it has a limit of R300. 但, I can still add prepaid airtime (with cellphone banking, nogal). No other service provider lets you do this!

Remember that R8000 cell phone I mentioned earlier? My plan is to get the Samsung STAR and spend less than R300 per month. I’ll have saved enough money to actually go and buy a more expensive phone (or laptop) with the cash I’ll have saved! 当然, if you actually use that R800-worth of phone calls, I guess the best available deal is where you spend the R19200 anyway. Maybe at least with a more critical view on your choices you’ll save yourself a good amount of money in future. Good luck in your search for your best deal!

相信我. 我们仍在处理正则表达式 – 只是在一个回旋处 (依稀实用) 方法. 这是一个如何在使用正则表达式去表达类似的方法偏离着手冲洗的DNS缓存一个漂亮的全面上市.

为什么我们要准确地清除DNS缓存?

有许多原因,清除 DNS 缓存, 虽然我相信这是最常见的:

  • 一个 内部网 服务有一个 私法 (内部) IP地址在公司网络上的时候,但它对于外部访问一个公网IP地址. 当您尝试从内部访问后从外部访问该服务, 有一个机会,你会缓存私 (无法访问) 知识产权. 一个良好的长期解决方案是使服务无法访问除了通过 VPN. 一个简单的办法是离开工作岗位工作. 😛
  • 互联网服务或网站改变他们的DNS设置和您的台式机/笔记本电脑在看 “老” 环境. 在这种情况下, 新的设置还没有 传播. 主机管理员遇到这种情况,很多时候.
  • 隐私: 如果有人可以跟踪你的DNS记录那就不是太难弄清楚你已经观看哪些网站. 虽然你已经看个人页面不能以这种方式进行跟踪, 主机名, 例如 “dogma.swiftspirit.co.za” 或 “google.com” 将在DNS缓存, 可能在你第一次访问的每个网站的顺序. 有更好的方法来做到这一点,虽然. 其中一个例子是使用Tor网络的所有DNS请求.

法拉盛的Windows’ DNS缓存, 从命令提示符:

有证据表明,前 视窗 2000, 视窗 操作系统的不缓存DNS结果. “ IPCONFIG 命令, 从命令提示符下运行, 被放弃了DNS缓存一些控制,此后就一直保持大致相同的.

如果要使用到的提示 视图 非管理员: 开始 - > 程序 - > 配件 - > 右键单击 “命令提示符” -> 以管理员身份运行

否则: 开始 - > Ř联合国 - > [CMD ] -> [ 行 ]

IPCONFIG / FLUSHDNS

Flush the DNS Resolver Cache in Windows

另外,也可以以清除在Windows缓存由 重新启动 该 “DNS客户端” 或 “的dnscache” 服务.

法拉盛Mac OS X的DNS缓存, 从shell提示符:

的Mac OS X, 苹果 苹果s有已经运行基于Unix的, POSIX-兼容, 操作系统基于 NEXTSTEP, 本身最初是从含代码 FreeBSD的NetBSD的. Mac OS X使用 lookupd的dscacheutil 管理DNS缓存, 根据版本.

为了得到提示: 应用 - > 公用事业 - > 终端

(lookupd的|dscacheutil) -FLUSHCACHE

这是怎么啦? 由于每 部分 1, 该 竖线 表明无论 “lookupd的” “dscacheutil” 是可以接受的. “ 插入语 表明 竖线 仅适用于 “lookupd的|dscacheutil” 表达部. 从而, 该 ” -FLUSHCACHE” 是不可选的,并且必须被包括在该命令,以便为它工作. 请注意,这些命令不产生输出,除非有错误.

使用dscacheutil如果你使用的是Mac OS X 10.5 (豹) 或更高版本.

的Mac OS X:

lookupd的,FLUSHCACHE

的Mac OS X Leopard的:

dscacheutil-FLUSHCACHE

Use dscacheutil to flush the cache in Mac OS X Leopard

还有一个GUI工具, DNS冲水器, 它会自动使用正确的命令可用.

法拉盛的Linux / Unix’ DNS缓存, 从shell提示符:

N.B. 如果您还没有任 捆绑 (启用查询缓存), NSCD, 或安装dnsmasq的和你的* nix的桌面/服务器上运行, 你很可能 不缓存DNS在所有 并没有什么冲洗. 在这种情况下,你会利用你的DNS服务器为每个Web请求, 可能放慢您的网络体验。*如果是这样, 我建议至少安装NSCD,因为它是最简单的设置. **

法拉盛NSCD缓存

作为与Mac OS命令, 这将产生绝对没有输出,除非有一个错误:

(|南 )(|/usr / sbin目录/)NSCD -i主机
  • 使用 如果您还不 否则第一选择是空白.
  • 指定/ usr / sbin目录,如果NSCD是不是已经在/ “路径”. 如果您分配一个陌生的地方已经NSCD, 首先找到它:
找到-r斌/ NSCD $

请注意,上述 “斌/ NSCD $” 本身是一个正则表达式. 🙂

使用NSCD, 无效的 “主机” 缓存, 登录的用户:
须藤NSCD -i主机
使用NSCD, 无效的 “主机” 缓存, 以root身份登录:
NSCD -i主机
使用NSCD, 无效的 “主机” 缓存, 以root身份登录, 指定的全路径:
/usr / sbin目录/ NSCD -i主机

冲洗绑定的缓存

要刷新绑定的缓存, 我们通过发出命令 rndc的. 使用sudo,如果您还不是根:

(|南 )rndc的冲洗

重新启动cacheing服务也适用!

以下是如何重新启动或者缓存守护进程:

(|南 )(服务 |/等/(RC 。ð|RC  .d / init的。ð|初始化。ð)/)(捆绑|dnsmasq的|NSCD) 重新开始

这开始变得难以阅读. *** 幸运的是我在细节已经解释:

  • 与前面的命令, 使用sudo,如果您还不根.
  • 第二选择具有第一选择 “服务 “. 这主要适用于Red Hat / CentOS的和Fedora系统.
  • “ “/等/(RC 。ð|RC .d / init的。ð|初始化。ð)/” 需要进一步扩大. 这是大多数其他系统. 通常, 在rc.d中是,如果您使用的是BSD风格的init系统 (例如: Arch Linux的, FreeBSD的, 或OpenBSD的). 肯定知道哪个命令使用最好的办法是“定位’ 正确的NSCD或 dnsmasq的 路径. 大多数Unix系统, 甚至的Solaris, 使用NSCD:
找到-r  .D / NSCD $ ; 找到-r  .D / $的dnsmasq ; 找到-r  .D / rndc $
  • 最后一个选择是与 “捆绑”, “NSCD”, 和 “dnsmasq的”. 这完全取决于它的安装和使用.
  • 的最后的图案, ” 重新开始”, 在指令给守护进程的控制脚本.

拱, 使用的dnsmasq, 重新启动高速缓存守护进程, 以root身份登录:

/等/ rc.d的/重启的dnsmasq

拱, 使用NSCD, 重新启动高速缓存守护进程, 登录的用户:

须藤/etc/rc.d/nscd重启

CentOS的 / 红帽, 使用NSCD, 重新启动守护进程, 作为root:

服务NSCD重启

冲洗Mozilla Firefox浏览器的内部D​​NS缓存:

Mozilla Firefox浏览器 保持性能了自己的DNS缓存. 火狐 2 只会缓存 20 最多的条目 60 秒. 默认设置为火狐浏览器 3 似乎是 512 最多的条目 60 分钟,这似乎更合理的每一天浏览. 如果你的桌面上有一个内置的缓存 (其中大部分现在要做的) 那么这里的缓存实际上是多余的. 我不知道该如何实现DNS缓存任何其他浏览器.

我找到了几个解决方案,当你需要清除缓存. 它似乎有很多方法可以做到这但是这些是最容易, 我已经投入优先顺序。:

  1. 安装 火狐的DNS冲水器 插件 – 提供了一个按钮来刷新缓存.
  2. 安装 DNS缓存 插件 – 提供了一个切换,禁用或启用DNS缓存.
  3. 清除缓存 (清除浏览器缓存和DNS缓存): 选择 Ŧools - > 明确 Private日期; 取消选择所有复选框,除了对C那; 点击 [ 立即清除隐私数据 ].
  4. 手工做的DNS Cache所做: 设置以下 2 关于:配置 选项 “network.dnsCacheExpiration” 和 “network.dnsCacheEntries” 至 0 然后返回到默认.

我有一个坏的缓存记录,我清除浏览器的缓存. 但它仍然给了我错误的信息. 是什么给了?

由于DNS是如何传播的作品, 你最好需要刷新上的DNS 所有 自己和之间的DNS主机 “权威的” 主持人, 开始的最靠近权威的主机的主机 (最远的远离你的浏览器).

作为一个例子, 如果您有缓存的DNS路由器, 重新启动您的操作系统的DNS缓存之前重新设置路由器的缓存, 只有 然后 你应该在Firefox中清除缓存. 原因是,即使你只清除您的操作系统和Firefox的缓存, 您的桌面仍然要问路由器,其 反正记录.

如果我的DNS服务器是在网络上我的控制之外的服务器?

你可以尝试暂时使用不同的域名服务器, 甚至可能是一个公开 服务器. OpenDNS的显示了如何做到这一点的一些好资料. 如果您想, 你也应该能够从自己的ISP就其解析的DNS服务器来获得相关的信息. 一个本地的例子 (南非) 是 Saix的列表 他们的解决DNS服务器.

* 可能的原因Firefox有一个DNS缓存内置的原因 ****

I think the Internet is a scary place. 是, me. Some days I find myself horrified to find the lowliest of criminal bastards trying to steal our livelihoods.

是, people, there are criminals out there and they want your money or they want to use you to make money. What’s even more scary is the lengths to which they are willing to go, even risking YOU. Do not pass Go. Do not collect $200.

I received an email saying that I was being offered a job as aRegional Assistant” 和, though the details weren’t given, the email suggested that it was a legitimate opportunity. I replied asking about where they’d received my details and also about what they would require of me.

Being the skeptic I am, I thought I could spot scammers a mile away. How fortunate that I can still laugh at the idea.

A few hours later, they replied indicating that I’d soon receive further instructions. They’dprobablybeen referred to me by a friend and they had a pile of referrals and so couldn’t specify which friend had recommended me. I waited patiently and left it to the back of my mind. “They’ve probably found a good candidate already and I’ve lost out”, I thought. “How nice that a friend might refer me. Obviously I’m Awesome.” (and daft :-/)

So later on, I receive my email with myfurther instructions”. This is where I finally realised that I was dealing with scammers:

Hi. We’d like to start a trial task. Our customer will make a bank transfer to you this week. Please go to our site <site omitted> to submit the banking details where the transfer will go to. Once we’ve established a good transaction history, you will receive between 2-3 transfers per week (amounts of about R10 000 each except the first trial transfers).
Please confirm that you can start. We don’t send any transfers to your account until we receive confirmation from you.
On Monday you will receive notification, detailed information and instructions regarding the transfers. Thank you and have a lovely weekend.

Say what??? I checked out the web site in question and, without a doubt, this is a money laundering scheme done by professionals. They know what they’re doing and they probably launder millions every month. What’s more is that, inevitably, they will screw you over and get the cops to arrest YOU. These criminals can leave evidence behind implicating you even if all you’ve done is diligently moved money from one place to anotherand kept a small percentage for yourself. 😛

Money laundering is where illegitimate money (stolen, probably) is transferred via third parties to appear more legitimate. You’re an accessory to the crime and, even worse, you’re even likely to be the victim of it. Recognise when an opportunity is too good to be true. I was fooled for a short while. Next up, given that a victim might give out a lot of personal details, the scammers might steal your identity and start to implicate you in fraudulent activities without you ever having done a thing.

If you happen to have already given any details such as the above where they wanted my banking details, contact your bank and inform them of the situation. They will give you the best possible advice on what to do next. If you’ve already responded to the mail but haven’t yet already given them the information they want, don’t reply any further. I’d also suggest calling your local police for further advice.
