Poor Service Delivery Cell C

I've had a contract with Cell c since 2014. Added a 2nd line in 2015. 2nd line was cancelled in Dec 2016 and cell C was notified however someone **********ly reactivated the cancelled line . I contacted Cell C immediately when ********** line came into my attention, they advised me to submit an affidavit and proof that I hve been paying for the ********** account. I submitted same at Northgate Cell C . I was told it would take 24 hrs to resolve my issue and get my refund . A month later when I followed up nothing was done so I had to resend same documents to Customer service . I sent on the 9thof October however to this date I have not heard from Cell c . I can't stop Debit other from Cell c cos I have an active line that I need to pay for and I don't want to mess my credit score but cell C' s delay is costing me money which I'm not responsible for . Why must i be penalised for an account I ddint open ? When is Cell c gonna stop the ********** contract and refund me all the invalid debit orders ? This is frustrating. Query ref ********** 652
