Cancellation of contract

I took a contract with cell C 2018,which I then transferred to my partners name. There were 2 SIM cards both on contract. For some unknown reason,the cellphone contract was successful switched from name to my partners name ,and one SIM card was never switched. Took time out of my busy day and I went to one of the stores,to cancel the data SIM card,I was then told the store can not assist ,I need to call the call Centre I phoned the call Centre ,I was then told “I do not have contract,they can not assist” I asked my partner to phone ,he was also told “He does not have a contact “they can’t I have been phoning Cell C call centers for months with no help. Every month I get charged a debit order ,any day and there’s unfortunately no funds in my account ,as a result of this my bank charges me a penalty fee for returned debit orders I need to cancel the data sim ,plus you need to refund the penalty fees I have been charged
