Phone not repaired after 3rd time of asking

<p>Purchased a Sony Xperia X compact in December 2016 from voda world </p> <p> </p> <p>In March the phone started switching off when I locked it, got hot, and also had the WiFi and Bluetooth acting up.</p> <p>Took it into voda world, took them a few days, i picked it up, lone behold, as soon as I locked it, it did exactly the same thing, but actually worse. Took it into Vodacom Centurion as I did not have time to get to Midrand . it took them about 10 days, i got a call to say it has been repaired .Besides the fact that i never even received notifications that my phone had been booked in, they apparently assessed it, found no fault and gave it back to me . Before I even walked out the mall, the phone had already switched off 5 times, with the battery jumping up and down . I walked straight in and sent it for repair again. I am extremely frustrated as I paid quite a lot for the phone, it is my business phone, and it is still under warranty. Why can vodacom not just replace it and make it Sony's problem. Come October, i will definitely not be renewing my contract and I'll move elsewhere . If i get my phone back and am told it is fixed, i will simply cancel my contract </p> <p>Please sort this out, i am not unreasonable and have been more than patient </p> <p>Job number ********** 0</p> <p> </p>
