MTN is *****ing my money!

Could you please check the following ref#1- ********** 7176? I received a call from one of your sales agents, Elijah, on 30 August 2018 who renewed my contract and informed me that my new amount to pay would be R248 per month for both the phones on my contract. (ref RO_C***.wav) Since then my monthly deduction has increased to R360! I called your service desk at the beginning of November to resolve the issue and after been passed from one person to the next I was finally assured that the problem had been rectified only to find at the beginning of December that once again R360 was deducted from my account. Since then I have sent numerous emails requesting feedback without any response. I have been with MTN for many years and quite honestly I have never received bad service like this before. This is either **************** or you have staff that are not trained to resolve such issues. I would like to once again request that this issue be resolved. I was told by your sales agent that I would have R248 deducted from my account on a monthly basis for the service. I expect that promise to be honoured. Failure to respond promptly to this long overdue issue will result in me escalating this matter to higher authorities.
