Cell C customer service is useless and pathetic!

Pathetic. All I did was change my bank in August, I gave Cell C (and all my other debtors) notice in advance before the next debit order date with my new banking details. Every ither company was able to debit my account except Cell C. I realised there was an issue when I got a message in September and phoned about 3 times to get the debit order set up on the new account. Eventually I made a manual payment when my line was suspended. Then end of September again they was unable to debit my account so in October I paid manually again and phoned several times to emsure the banking details and debit order date are correct for end of October. Now it is November, again they did not debit my account. Again they suspended my account. I have phoned twice in this last week and again I have had to pay manually. I sent the proof of payment to a fax number I was given but my account is still suspended. I spoke to a ***** consultant tonight who AGAIN confirmed my banking details. Then told me they cant find my payment or proof of payment, I need to resend it. So now they cant reactivate my line. And also theres no way that they can help me with my debit order problem I need to go to a police station, write an affidavit stating that cell c is the only stupid debtor that cant debit an account when you change your banking details and then take the affidavit into a cell c store and every month go and pay cash??? Is that convenience and good customer care?? Thats why we have things like debit orders, I dont have time to go police stations and into the store every month!? You will find my proof of payment amd reactivate my account by the end of this week or I will pay up both my contracts with you and my fiance will pay up his contract and we will move to another network provider that doesnt treat its customers like ****. I have to beg you guys to take my money now I have to beg you to reactivate my line which I had to pay manually because you guys are idiots??
