Shocking service from Cell C

I was contacted to have my contract upgraded which i have done for many years before with no problem. This time around the consultant issued me with a new contract which included a new phone and new line which was not what i signed up for. I have contacted Cell C so many times and everytime i speak to a diffrent consultant and told that within so many days Cell C will contact me to resolve the issue. I received the new phone on 21st April. Started calling from Monday 24th April to lodge my complaint to date am still waiting to resolve this matter. I am totally disgusted with the service and would think a senior manager or supervisor would have made contact with me by now but nothing as yet. I have been billed already for something i did not sign up for. A total mess up from the consultant from Cell C. I would not recommend anyone to them. They quick to send bills but cannot resolve issues as quickly as that bills come. Totally dissatisfied with the service
