Cell c is Pathetic

At this time I'm very fed up with Cell C. I have tried canceling my contract since June and every time I tried to cancel I was told my account is in arrears. Fine.. I waited for July debit to go off but was told same story again and I tried to ask for which month I get stories that don't make sense and every time when I call I get different amounts that I'm told it's in arrears. Last week I tried to follow up again as I receive sms again saying my account is in arrears, I requested to speak to a manager and a consultant went put me on hold and spoke to the Team Leader. She came back with the response that my account is supposed to be up to date with the payment I made in July. I was requested to send a proof of payment which they confirmed it has been received and up to date I'm still waiting for an update. I'm tired of following up and I still can't make outgoing calls or use data, worst of all my name is on bad credit record because of Cell C ***********. I'm disgusted by Cell C, your consultant even has a nerve to call me today to offer me an offer and when I told him I'm okay I don't want it he keeps going and on forcing me, I even explain that my line is even closed but he kept going on that everything looks fine from his side. Cell C is no longer a good Network Company I used to know when I initially opened a contract with them but it's just Circus playing with our money.
