Pathetic service and rude attitude from the staff.

I did get in touch with Cell C and told them I will be making payments via Nedbank.Cell C used to debit my account whever and whatever amount they felt like taking out.This is the reason why I do payments via Nedbank.I did phone in and told tha customer care staff as to what transpired.Thereafter every month I make payments via the bank.The contract is for R139.00 but yesterday I made payment of R140.00 which went through.Today my daughter calls me to state that the line is suspended cause there is an amount of R 74.69 outstanding.I called the call centre and spoke to a consultant which was not helpfull and told her that I did phone in and also gave in writing about the payments going forward and this rude lady did not want to understand what I was talking about. I have reached the stage whereby I want to take this case further with ICASA as I have had enough with Cell C from the very begining. Now I am making the payment of R74.69 and I want the line re-instated by tomorrow latest or else I am sending this conversation to ICASA and will ask them to pull put the records from Cell C.
