MTN took my money (and acknowledged it) and is refusing to refund me

<p>I cancelled my MTN contract in Oct 2017 and was a pretty content pay-as-you-go customer for about 5 months when a debit order hit my account out of nowhere for the old contract amount from MTN. After literally hours on the phone and demanding that I be refunded they said that they can see I cancelled my contract in Oct and would investigate but they cant do anything else. In April another debit order from MTN hit my account and so I contacted the call centre again and had to spend hours explaining the situation over and over. After about a month ( and several calls to the call centre) they acknowledged that it was a mistake and committed to repay me within 30 working days. After about 60 working days and multiple calls without a refund they told me that the they have credited my account and did not refund the amount into my bank account ( as I had explicitly requsted). The call centre in Jun requested that the credit be paid out into my bank account....which MTN is refusing to do!! After 3 months,numerous calls, escelations and promises later the call centre told me that they cannot do anything as it is the refund department issue and that I should just shut up and wait. Clearly MTN is refusing to repay MY money that they acknowledged *****ing and they keep treating me like *******. Also, if anyone is reading this, would you be able to point me in the direction of the government department that handles POPI act infringements?...as this is clearly a case where MTN kept and used my personal information that directly resulted in damages to me.</p>
