Paying for a phone MTN will not deliver

I upgraded my MTN contract phone via MTN direct in May, the phone i got was faulty, I took it to the repair center in Midrand on the 6th of July, the phone was approved for a replacement phone and I have been waiting for delivery for 8 weeks now. After 2 weeks had passed and i still hadn't received the new replacement phone i called MTN and was told they couldn't locate the phone i had returned in their warehouse and would only release the new handset once they'd located the one i'd brought in. This shouldn't have been my problem, internal MTN processes should not impact on their clients. Each week since then I'm either told the person that is dealing with this will call me, should call me, will be advised to call me. Meanwhile i'm paying for a handset i do not have and have no idea when i will be getting. As if this isn't bad enough, on two of the ocassions i have called MTN direct who I think have subcontracted CCI Liberty, the call center agents have actually put the phone to the side so i was actually speaking to myself!!

I have been a customer with MTN since 2000/2001, i am ready to cancel my contract with them. A couple of years ago i cancelled my data contract with them and have not looked back since. The gross shoddiness of the service has been shocking and i believe it actually borders on breach of contract as i am now paying for a phone i do not have.
