Bad service

I have been having problems with cell c for a while,they didn't debit my account 3 months back and I only found out when I could make calls,I phoned and asked why am I blocked and was told it was due to non payments asked them how as my account had funds .I asked them to debit the following day and they agreed and my line was active again.2 weeks later I noticed that they didn't debit and again had to call cell c was sent from pillar to post until I threatened that if they don't debit I will take this further.A debit order went off and again last week another debit order off.Today I get a call from Kutlwano telling me that I'm in areas.What areas are you guys on about.Am I not the one who begged you to debit your money then now you come back and say I owe you guys.Can this Kutlwano lady send me proof that I owe you guys like I told her during the call
