MTN Billing Nonsense

MTN changed their data allocation and billing cycle and on the 5th December debited double what normally comes off the account. I called the call centre looking for answers and after waiting for 10 minutes, the agent explained that due to billing change I was charged for 1 month in arrears. She was very apologetic about this, but I asked to speak to somebody in accounts. I got put on hold again and eventually spoke to one of the rudest people at MTN, a Robert Bongani. She explained that an SMS was sent out to inform clients of the change. It's ludicrous to communicate a huge change like this via SMS and also to do this in December. I asked what her job title was (Credit Controller) so I could check who exactly I was speaking to. Seems her form of training was to now become arrogant and ask for mine. MTN instituted a stupid change, which has a lot of people paying extra, during the worst time of the year. Whoever approved this should be denied a bonus at the very least.
