Over Billing!!!!

I have been trying all day to contact Cell C to query my most (and ridiculous) recent bill, and no one is answering the phone. They have over billed my account (the second time in the space of a year). And I still don't receive itemized billing as I initially requested when I signed up with them. How *****ic could a group of people be? Is this how they get away with over billing people? by hiding the items they 'supposedly' used? I have proof of the call times and duration, as well as data bought and used to back my query up. I have had it with Cell C and I will no longer associated with it. <br> <br> Send me my itemised bill before you even call me. I've spoken to your consultants before and they don't even know the difference between bill types or bill cycles. I'm not in the mood to be insulted once again.
