Phone returned from repair centre with same problem

<p>On the 15 May 2016 I took my HTC one M9 for repairs as I was experiencing problems with the software. After I collected the phone, a few days later I was experiencing the exact same problem. I had to book the phone in again for repairs which means I'll be without a phone for a few weeks again. Such bad service seriously having to be Inconvenienced in such a way of driving back and forth, for a contract which Im paying R523 a month(with a phone I'm constantly having problems with). Seriously questioning the service which Vodacom provides.</p>
