Cell c is a ****

I'm being charged for penalties that were not my doing. I have set up arrangements with them for my new contract but no one seems to know what is going each time I ring them. No one was willing to raise a complaint for me each time I called and asked they raise one for me. Sad thing is no one bothers to call me back. I have been trying to get this sorted since the 31st of August when I started being **** to.
