Atrociously bad service

I cannot explain in words how absolutely helpless I feel. I have had an ongoing problem with Cell C for the past 4 months since the inception of my cell phone upgrade. The upgrade took place along with 3 other contracts which was either I am assuming fictitiously added to my name or either the Call Centre Agent was seriously lacking in skill and was unable to do his job properly. Regardless, Cell C then proceeded to punish me for their error and although it was agreed upon that the new contract amount would only kick in on the 01/06/2021, I received a bill of R860 in March already. So at that point, I was paying for my existing contract, the upgrade and the 2 fictitious contracts. I was instructed to submit an affidavit because I had no knowledge of the other 2 numbers added to my name. Cell C has however written off an amount of R4000 plus which is a supposed cancellation fee for one of the fictitious contracts and they had the nerve to tell me to write a sterling review of their service on Hello Peter whilst they are still charging me for the contract/s that was apparently written off. I have made many enquiries with the Call Centre and am simply told your case is too complex and we cannot help you. My credit record is being jeopardised by Cell C because they are sending inaccurate information to the credit Bereau about my account being in arrears. I don't understand why I must be penalised for Cell C's incompetence. Upon calling the the service number: 084135 - the operator informed me that my number has been suspended. Cell C I am at a loss for your pathetic service!!!!
