Got a phone on Contract from MTN and since September 2015 the phone was booked in for repairs as the speaker was not working.<br> MTN told me that they had to replace the phone (CAT BISQ) as they are not able to repair the phone, and guess what??? NO PHONES IN STOCK!!!<br> I now have pay for a contract phone which I CANNOT use.<br> I have been phoning the Call centre almost every week and guess what?? NO SERVICE!!!<br> Phoned the Call Centre again on 28 October 2015 and spoke to GURU responding with a BAD ATTITUDE... NO STOCK!!! and she cannot confirm when stock will arrive.<br> I am not paying one cent towards my contract until this issue have been resolved. How can I pay for something I do not have?<br> How long do I have to wait for a new phone?<br> I cant even use the Sim Card as I don't have a phone to put it in.<br> This issue needs to be resolved asap!!<br> Please do not contact on the contract number as I don't have a phone.<br> Please phone my wife on number provided below!!!
