Good day i got a Sony Z3 compact 6 months ago on contract with mtn..a month after i had it the back cover cracked in my pocket i went to mtn and they said it will cost R1500 and R2000 to fix it even though its not my fault .I decided to just leave it coz i didnt crack the screen due to negligence im not gonna pay for the cover and after googling i saw cracking of screens is a common problem with the sony z3 but the supplier keep on hiding behind the physical abuse clause even though it wasnt even the client's fault. So 2 weeks ago my phone started shutting down by itself and after a couple of hours it switches on again. i went to mtn regarding this problem they didnt want to book my phone in because they said Sony will not repair it they will say it is physical abuse even though it happen months ago and the cracks got nothing to do with the problem. They said 1st i must get the cover fix then bring it back for the problem im experiencing..they said i must go to sony for the cover,they guy in the store even suggested i take it to a pakistaner(pathetic)...I did contact Sony and they send me back to mtn and now i'm paying for a phone i cant use and no one even trying to assist me
