Most ******* and *********** Network

For nearly 12 months I've had to deal with Cell C and there incompetence. I've been paying for a year on a simcard i no longer have and when I get to through they tell me they smsed me the information to my contract number that no longer exists. Repeatedly I've asked to be emailed or sent a sms on my current number but it just falls on deaf ears. Now they don't want to cancel my contract and after numerous calls they tell me it's only been cancelled now after it was supposed to have been cancelled end of august, and they can't send communication to me and I still owe a R69 for usage. What usage!!!! I've been paying for something I haven't had in 12 months. Your service is despicable and then your unsympathetic agents have the nerve to offer me another contract.
