Unacceptable service

I handed my phone in for the screen to be replaced on the 5th of December in Cape Town. I moved to Johannesburg at the beginning of the month for work. I phoned cell c on the 27th of December to notify them of the fact that I have not got my phone back and that they must please not send it back to Cape Town as it had already been sent to the repairs department in Johannesburg. I have phoned about 15 times since then to find out about the progress and when my phone can be collected. Yesterday I waited for 45 minutes for my call to be answered to be told that my phone is back in Cape Town after which I was promised that it would be sent with the courier today and be in Johannesburg by Monday or Tuesday. This afternoon I got an email from the branch in Cape Town telling me to collect it so it obviously hasn't been sent. I then spent a whole hour being sent from person to person by the call center as well as being given the incorrect number for the call center. I have sent 5 emails today. None of which have been rep**** to. Eventually get through to someone who tells me my call from yesterday has not been recorded phone is still in Cape Town and nothing can be done about it until mon
