HORRIBLE SERVICE

If I could give 0 stars I would. I've had numerous problems such as I signed a 24 month contract for a certain amount but cell c will then deduct extra money after a few months. I have a contract which is paid every month but they cut my network reception where I can't make phone calls, sms or use data. I wrote to customer care, which is the only way I can communicate with them as my number is not working. They just don't reply. I think this is ****************. They should be ashamed of themselves.
