Telkom accounts department

I have had a cellphone contract with telkom since January, In the first month I signed up for a debit order, I was informed that this will be affective immediately. I then recieved an sms saying my account is in areas, I called the customer care they then said it will only be affective in the second month. I paid manually. Second, third and fourth month u was debited without a problem. Fifth month came and I was not debited, I recieved an sms saying I was in arrears and my account would be suspended. I called customer care and she said they cannot debit me now and I must pay manually or they will double debit me. The whole of last year I was being debited only every second month, which was very frustrating. I have been in store multiple times and they say they don't deal with account queries and we call customer care together to "sort out" the issue. This year I have not been debited at all, I called today and requested to cancel my debit order and I will pay, I was told that they do not do COD only debit orders and that I must go to my bank as it is my fault. Do not open a contract with telkom as you will have constant issues.
