Billing and not feedback on complaint- 5REQ***

MTN debited my account in June with +_ R2500. I returned the D/O after confirming the outstanding balances at the MTN office at Campus square (R547). I paid the funds electronically to Absa Bank as as provided by the consultant. I visit the Glen Branch and logged a formal complaint with MTN and requested to provide me with the evidence - sites visited and usage on the account. I paid MTN again on the 1/8/15 R583-01 and R1900 on 31/7. Left a message for a call back for Manager. No feedback received at all. The Manager called me once in July to confirm that they still awaiting feedback. I visited the Glen branch again on the 15th of August to apply for a new wi-fi modem for my kid that is still busy to study but was not supported due to the outstanding complaint. I called the call centre on Monday to log another complaint - but the consultant sounded so ***********.. Visited the Glen branch on Tuesday -no feedback as yet. MTN you are busy to mess up my credit record! I indicated - cut the number and mess with my credit record and I will publish your bad service!!. I had enough. Please wake up and deliver customer service!!!! The strike is over!! Feedback please!!!
