Doesn't care about customer, I cant get sevice.

I have a Nokia Lumia 1020, after about 4 months of having the phone, it stopped working, wouldn't turn on or charge. So they sent it to the repair centre in midrand. I got the phone back 10 days later. Then 2 months later the phone broke again, the same problem. I sent it in again. 20 days later I got it back, when I went to collect the phone I asked the manager (at my cellc shop in gardenroute mall) what will happen when it breaks again, she assured me that after a phone breaks a third time, they will replace it. It broke for a third time, 2 months later. They did not replace the phone and when I refused to take the phone. They had it tested and found that the phone was not in working condition. So they sent it in for the 4th time. Its been there for 2 months now.I called everyday and insisted on a new phone. My local shop just asked me to call callcentre myself and providing me with no sevice. Now Cellc finally agreed to replace my phone, they once again dissapointed me. Today, 3 weeks after they told me they are sending a new one and no one can tell me where it is. I am so dissapointed and frustrated. I want everyone to know that cellc is the wost service provider in the country
