INCOMPETENCE; CLASSIC CELL C OVERCHARGING & NO ACCOUNTABILITY

I am appalled at the level of service at Cell C. No 1. I have been calling in since January with no joy. ACC NO : *** This is the 4th month I am being billed on my data account for "content services" that I didn't authorise. Each time I request that they reduce the credit limit to R699 which is the amount I contracted for but no, its too difficult for the calibre of staff they employ, so now I am R800 in the hole already with no end in sight. No 2. I decided to cancel the contract due to all the issues I am having. They told me its a contract and I must pay cancellation fee however when I took the deal it was month to month, AND it states that on the statement. My only choice is to block both debit orders until someone comes back to me.
