Refund Outstanding

I had payed up my contract in the 15th October 2015. Included in the payment was current and unbilled invoice, which meant contract was up to date. This was confirmed by Thabang Katume when my contract was closed and converted to prepaid.<br> <br> End of November 2015, MTN decided to debit my account for R425 - which returned unpaid as i changed my banking account. I never received an invoice for this. My contract was paid up to date.<br> <br> After numerous back and forth emails, eventually Thabang confirmed this was an error of MTN as they had cancelled the contract late. I was told to make payment as system shiwd account in arrears and promised that after payment was made, a refund would be issued 5 days later. Payment was made in 15 December... Today is 30th and i still have no idea what is happening. No one seems to help, and no one calls me. My emails basically do not get answered wih reference to content that is on the mail. Today i received a mail stating that my contract was converted to prepaid - which doesnt answer my questions<br> <br> MTN service is utterly dusgusting and pathethic. I experienced this level of service even when i queried cancellation. Everyone is totally unhelpful<br>
