MTN *****!

In September 2017 I saw on my account that there was a new contract taken out on my name of R799/month. I reported it as *****. MTN said I have to write an affidavit, which I did. Now since then I used my money and airtime to follow up on this case, because the amount still went of from my account each month. At last in May this year that ********** contract was stopped and my account rectified. I asked MTN that I want the money that accumulated over those months to be paid out to me. They logged the call, but the next month I just received credit on my account . I went back to MTN stating AGAIN that I don't want the credit I want the money. The lady logged the call yet AGAIN.... but still I received a credit. I received a statement last month stating a R4858.52 credit... still NO MONEY. I called MTN customer care line and the lady said that she did log a call, even gave me a reference number and that the money will pay out in 21 working days. Yesterday was 21 days. I called again. Another lady said the money is now R4010 but will be paid out in 24 hours. I mailed my banking details to her ********** com. When I called today another lady said that the money cant be paid out, because they now need to open a case to see if it was *****, coz MTN ASSUMED that I did an upgrade on my account. I said that I wanted to talk with a manager. They transferred met to Fezeka Mhlontlo . She said she is second in command there. She explained that they now want journals etc etc. and can only give feedback to me in 48hours. I have done EVERYTHING that MTN asked of me from my side and even spent more money on this case.... HOW is it possible that after more than a year they still can't pay me the money? This is unacceptable
