billing/incompetency

am utterly disgussted to say the least, receive the call from the Nelspruit branch to come and fetch my phone, and i was thinking and hoping everything was fine after the R330 which im still awaiting feedback on from Regional Manager, now phone still faulty, nothing was donr, and it has been 3 months full now, sice MTN had my phone, what do thy think im using for the past 3 months, confused. now it turns out that the Fing my iphone was not deactivated im told thats why my phone could not be fixed, how could MTN consultant advise me of theis and save everyone from this pathetic experiance i have with MTN. now the consultant took the phone awauy and advised me that i must wait again and they will advise me once the phone arrives again. im actually sickinned to have any dealings with such incompetency and inconvenience. im a paying customer, never skipped a payment to expeince such. Please MTN sort out this mess you have caused, and save the little if any respect i had. some one must please call me. im very frustrated here.
