Extremely Bad Service&Incorrectly Billed Owe MONEY

Hello Peter<br> <br> I am still unable to deal with MTN. This is my 3rd complaint for the exact same thing via Hello Peter. MTN has not resolved my problem. They owe me R 210.03 for the last 2 months, it was supposed to be fixed with my debit amount on 01 Dec 2015, they have failed to do this. I am being incorrectly charged R 92.11 every month! They were supposed to credit me for the previous 2 months, this was not done. I need my refund today! Not next month! I need to cancel my contract with MTN! The response I receive from MTN is POOR/Shocking!!!!! They are not solving my problem, every month I have to beg for my money. They just don't care about customer service at all!!!! This morning I received some stupid reply, nothing to do with my query. Explaining that any data I use will be charged to my account! I understand this, it's obvious that any additional data other than my 500MB that I receive will be charged additional to my account! This is not my complaint! I am being charged for the 500MB that I am supposed to get free as part of my entire package for R 669 a month!!!! I am experiencing the same problem every month for the past 12 months! This is unacceptable!!! I am fed up!!!
