Sony Expria sent in for repairs

My Sony Expria had a default and was advise that they would send it away for repairs and that it would take up to 3 weeks for the repair. After 5 weeks no feedback was received as to what is wrong with the phone or when I can expect it back. After phoning the MTN branch in three rivers numerous times, I was told that they are waiting for spare parts and that we must just wait until its back from repairs. It is now 7 weeks later an I still have not received any feedback as to the status of my query. <br> <br> I am fed-up with this bad service and would like them to keep the **** phone and cancel the contract as I feel this is breach of contact as I have to pay for a phone which I do not have.<br> <br> If they could have supp**** me with a loan phone, ot would have been a different situation.
