No Phone but still paying the contract

I was asked to upgrade my contract last year. It is almost six months, I am paying a contract that I didn't even receive my phone. I tried to raise this issue with mtn and they promised that they were going to give me my phone in December but till today, I have not heard anything from them. Every month my account is being debited even though I didn't receive the iPhone 5 I upgraded to over 8 months ago.<br> <br>
