********** account and unauthorised debit order

Last month I had a debit order go off from my bank account from homechoice, I reversed the funds and instructed my bank not to authorize any debit orders from them as I have no account or reference about purchasing anything from homechoice. Again this month an amount of R1478. 13 go off. I sent an email got a reference number and that someone will contact me back. Surprisingly I got a call from a lady who had an attitude about the matter,you told me herself that a ********** account has been opened with my details as the address and cellphone number is not the same as the one on the system. She kept on saying that I must reverse the money bank into my account and that she will get someone to send me a form that I need to complete and email them back so an investigation can be done. I'm not sure what more proof did she require as it was clear that I didn't get the goods I'm being debited for. I need this to be resolved as I cannot wait for 30-90days to have this matter investigated and resolved while my bank account is being debited every month. This this it will get me into major trouble as I keep reversing money and if payments are not made my name is going to get blacklisted for something I have no idea about. Please sort this matter out with a sense of urgency.
