Cell phone

I bought a Cell C Fantasy at Edgars Canal Walk on 30/08/2017.I took in as it just went dead and did not want to switch on again i was advised I would need to wait 3-6 weeks as it would be taken in for repairs I then went back today as was advised last week by one of the store assistants when I arrived I was advised my phone cam e back the lady took it out of the box and when she tried to switch on then phone i was still not switching on meaning it was never fixed the worst part is that there was no report to as to say why the phone was not fixed and I'm now without a phone for 7 weeks but I got no go service at Edgars the store lady advised the phone would need to go back in for repairs again I then questioned her asking will I now need to wait another 6weeks for someone that is not my problem she advised me she cant say as she still needs to escalate the matter,she advised she will call them to find out if there is any alternative I then asked her what would be the alternative she that advised she doesn't know as she doesn't not work at the repair centre I'm so disgusted with the service I got and I want the matter to be solved ASAP cause I'm staying without a phone for another 6 weeks I need an answer and soon or I will have to take the matter further
