FAULTY PHONE

I upgraded thru the call centre. I phoned Cell C & was disconnected each time, I decided to give up & phoned the next day to lodge my complaint, I finally got to speak to a consultant I told them that after 2days the screen started to malfunction, they refused to help & replace the phone due to my 7day concession period that expired the previous day. They told me they can collect within 7-14 days & 21 more days to decide what they will do. I explained that I work from my phone & cannot be without a phone as it is my income, I asked if they could give me a loan phone, but they could not. I decided to rather sit with the frustrations of the phone than be with no phone until yesterday when it froze & I cannot use it at all. I have a simple solution I will NOT pay my acc until Cell C have replaced my phone with a new one. All I ask is to take back the faulty phone & give me a new working one as I don't see why I should be penalised by having to sit with a faulty phone or no phone at all when Cell C sent me a faulty unit. I will not be held responsible for the acc just like Cell C wont take responsibility for the faulty phone they wont replace, BAD AFTER SERVICE THIS IS NONSE
