One problem after the next

<p>Last year I received my sony xperia z3. A couple of months ago the screen started flickering and the battery drains from 20% to 0% in a matter of minutes. So i sent it in for repairs at SSS cellular repair center in Johannesburg and they sent the device saying nothing is wrong but that something was loose inside the device and that they tightened it again. About 2 week later, the screen and battery started doing the same thing!!!! So, I sent it in again and they sent the device back saying nothing is wrong. On many occations I offered to send them a video I took that showed the flicker but no one calls me or talks to me. When i deal with customers, I call them back and tell them what's going. I would've appreciated a call saying "Mr Bothma, we arent finding any faults with the device. Can you perhaps tell me more about when this happens or how, or do you have proof you could send us?"...but I send my phone in, it takes 3 weeks to be looked at and then it gets sent back with nothing changed. The warranty is expiring soon, and I'm not going to pay a contract fee every month for a faulty device. Unfortunately my service provider, TELKOM, is useless and don't care that my device is faulty. Their managers just walk away saying "it is what it is". Hopefully this will reach someone who can understand my frustrations. Because right now I'm sitting with a faulty device and no one seems to be able to help me. And i'm paying good money for this device.</p>
