problem with account

<p> I have been receiving calls from Vodacom to cut of my service because of an outstanding amount, while there are no arrears outstanding on my account. Vodacom decided to deduct an amount of my account from a bank account that does not belong to me. Then after a penalty because there were no money in that account, decided to pay back that amount into the same account????? According to them it was an technical fault that affected a lot of Vodacom customers. Can it be a ****???? After numerous calls to different people I eventually reach somebody that told me I have to go to the bank and get a letter stating that the account does not belong to me. Now I have to sort out a problem that is not even my fault. </p>
