Pathetic Customer service from MTN!!!

On the 26/08/2015 I've placed a complaint on Hello Peter with regards to the poor customer service I have received from MTN. A Mr. Timothy Clouts contacted me telephonicaly the 27-08-2015. He also reported on Hello Peter on the 27-08-2015. He requested that I fax all the correspondence to him with regards to the billing issues and the faulty handset that is currently still with MTN. I faxed all the documentation through on the number he provided. In fact I faxed it twice to ensure it had gone through. I faxed the faxed delivery noted to proof that all the previous faxes was also delivered. No surprise here consumers!!! to date I have not received a single word with regards to this matter. MTN's so-called responses is clearly a method to calm customers into thinking that the matter is being dealt with. in the interim I have cancelled another contract with them. only 2 more to go that I, a customer of 15 years will be rid of them!!!
