Promised callbacks never happen

In the last 2 months, I was mistakenly upgraded by a mtn store, who used my number with an upgrade. After 3 weeks of me calling constantly did I manage to get someone to assist me. No feedback given, and everytime I called in I had to re-explain everything again.<br> <br> Finally the erroneous upgrade was corrected, there was some form of apology (hardly) and I was told I could upgrade my current contract. Which I did...<br> <br> Then with my latest bill I find that MTN are still billing me a hardware charge from my old contract - evern though I was told that this would not be the case thanks to their previous upgrade mess...<br> <br> Again I called the call centre, emailed and filled in the please contact me form on the website... a week has passed and no one has called me back regarding this.<br> <br> Absolutely pathetic service from MTN... it is so easy to keep a customer happy.. FEEDBACK!!!
