Device replacement taking too long

Hi<br> <br> I initially sent my device for repair in February. The device came back with other issues ( screen brightness inadjustable, sim card slot not working etc). I returned the phone on the 30th of March 2016. There was no feedback from Cell C. I had to phone every time to get the status of my device.<br> <br> I was informed that my device will be replaced but till now I'm still waiting. Follow up is only done while you're still on the phone. You end the call, nobody follows up. When you call again, the next consultant will ''follow-up' again.<br> <br> This is so unfair and unprofessional. Every month I'm paying for a device that's probably sitting in some technician's bench in Johannesburg. These ''out of stock' excuses are really annoying.
