Ridiculous data charges

<p>Today I retrieved my invoice for the month May and I was shocked to find out that MTN has charged me 1264.38 when I still had data. When I called the call centre I was simply told that a call will be logged and I will only get a response in 7 days. When my data bundles are up I get a notification that I have started incurring charges and I would then purchase data bundles, and no notification was sent my MTN in this regard. This is not the first time this has happened and this first case was never resolved and all I was told was that due to the strike action at the time they couldn't assist and resolve the matter months later nobody cared to follow up on this and my complaints seem to have fallen on deaf ears, whilst MTN smiled all the way to the bank as they automatically debited my account notwithstanding the unresolved billing issue. I have 3 account with MTN and I cannot wait to move over to another service provider and port my number.</p>
