Failure to Debit account

In Mid June, I take a contract with Cell C and was given a new phone. When 31 July came, I notice that cell c didn't debit my account. When I called the customer service, I was told that the bank had stop the debit. After making arrangements to debited on the 3rd of August, I than called my bank to check why the debit was stop. To which I was informed that Cell c hadn't even tried. On the 4th of August, I call Cell c customer service again to inform them that the debit hadn't gone of. I was told that the bank had stop the debit again. To which I told the call center agent that they hadn't even tried to debit me. I than told that the branch code was incorrect in the system. Once again I made arrangements for the debit to go off on the 5th. On the morning of the 6th, I called the customer service again to inform them that the debit hadn't gone off. I was than told once again there was a problem with branch code. And made arrangements for the debit to done on the 7th. On the morning of the 8th, Cell c sent a message that my account is been suspended due to failure to make payment. I than called customer service again and informed them of the message and the many calls I had made with regards to not been debited. I was than told that the system had failed to verify my banking details and debit will be done on the 11th. I am writing this review today to say that my account has not be debited and that Cell c has not resolved this matter and that they do not care.
