BAD CUSTOMER SERVICE !!!

Since May 2015 I have been trying to get an account sorted out and a faulty phone still on contract fixed. Both matters still not resolved. The phone was given back to the branch the contract originated at on the 11/08/2015 - to date NOBODY contacted me. I have faxed all the correspondence dating back to 09/06/2015 to the MTN Head Office - ***/3131 - 2 x times thus no response to several direct faxes, several e-mails and phone calls to the services centre and several visits to the local walk-in centre and MTN stores. PATHETIC!!! I have been a customer since January 2001and we have 5 x contracts in total. we have cancelled 2 x thus far and will be cancelling the rest shortly. I have opted to rather use another SERVICE provider and will be moving all my contracts there. I will rather spend a few rand more and have peace of mind than endless troubles and NO CUSTOMER SERVICE!!!!!! I cannot express my disappointment in MTN after 15 years of being with them!!! MTN is showing no interest in getting customers queries resolved - this includes getting charges not used sorted out on accounts. I have kept copies of all the E-mails, faxes etc. and the handset is at the local MTN store
