Unauthorised debit order going through my account

I recently discovered that a company called Marstercare Early Bird has been debiting my business account. I have no dealings whatsoever with this company and as such notified the bank and demanded they return my money into my account (approx R9000). The bank returned the last two debits into my account but charged me for the service. Then they proceeded to tell me that they would charge me even more to get the other two debits reversed. They actually suggested that I speak to the company in question and deal directly with them to try and get the money back. Guess what...Mastercare are not interested in oaying me back my money, I am opening a theft and ***** case against them. In the meantime I am of the opinion that the bank did not have authority to pay Mastercare the debit order because I did not sign for such a transaction, I have no dealings with Mastercare. The bank says not their fault. I am approaching the Ombudsman to see what I can do. In the meantime, be aware that the bank can debit your account and pay any *********** that has your banking account numbers (your clients employees could get access to this info, easy peasy) and claim not their fault. Outrageous!!!
