MTN REFUSES TO PAY MY REFUND

I've been dealing with 5 different people (2 supervisors included) regarding a refund that was supposed to have been resolved over a month ago, with my first interaction being on the 17th of September. The initial issue according to the first supervisor I spoke to was the incorrect logging of my request, which consequently delayed process. The first supervisor in the call centre (Sipho) assured me that the query would then be logged correctly...however this appeared to not be the case. I was then called by a supervisor in the credit control department (Yvonne) after I inquired about the refund again. She basically threatened me as this wasn't the first time they were scheduled to pay a refund into my account, stating that they had a backlog and that this should be the last time. We both agreed that she would escalate my query if I agree that no other refunds would be requested by me due to overpaying my account. This month I kept my end of the agreement by not overpaying but I still haven't received the funds. I was then informed by Yvonne's (supervisor in credit control) colleague that the request was logged incorrectly again, however that this would now be finalised. To date I still have to call to find out what the hold-up is as Yvonne refuses to speak to me nor call me back. Her colleague Mpho Seshabela has also not been providing me with any feedback willingly as I need to constantly call her. In the meantime my financial status is worsening as I'm need of the funds you people refuse to pay me. I have already spoken to my colleagues at the Department of Education to cancel their MTN contracts & will continue to do so at other Departments until I receive my money as more and more people are experiencing terrible service from you people.

I've always paid my contract on time and can't understand why MTN can't keep to your end of the bargain...I will escalate this further if I still haven't received my monies by the start of next month.
