MTN- Handed me Over, Incident No not resolved

There has been a query on my 3G Data since January 2014 and MTN has not provided me with the necessary evidence as per my logged incident, I have 3 Reference numbers to date and no calls or feedback as such. I have been recently informed that my Account has been handed over to MBDC and my Profile update month credit Bureau. I find this to be unaccepable. Firstly My account is currently sitting at R37000, Secondly there was a limit on my account Set at R2000, and thirdly when the first months billing was high I logged the incident, pleas check voice recordings and incident numbers to validate. Why Am I being penalised for the inefficiencies of your office?<br> 14 January 2014 : at 2.21pm spoke to Sheldon, Reference number : REQ***<br> 5 February 2014: Spoke to Lindiswe Kuswana<br> Went into the MTN Store in Morningside, Reference number : REQ***<br> <br>
