Appalling Service !!

I am appalled at the level of service received from Cell C. I signed up for a contract at the end of April and requested a Violet phone. There was a delay in the delivery and when I eventually received my phone, it was the wrong colour and furthermore no SIM card was included. I called the call centre and they promised me that someone would contact me within the next few days. Needless to say, I waited 2 weeks. I then called again and was transferred to someone that initially said they couldn't assist and would get someone to call me back.It was only when I refused to wait again that the very same person said that they would log a call for a Manager to contact me. I have not been contacted by anyone to date and merely received an SMS saying that I must buy a SIM card and RICA register it and that the color of the phone is not guaranteed. I have been paying for a service since April and have not even been able to use my phone. What kind of service do you offer your clients, CellC ??? Let's hope that I can speak to a human being wrt to my query this time and get it resolved once and for all!!!!!
