Money Missing

There has just been a debit on my Husband's Account yet again of R10000. When drawing a statement it says Journal debit RCCS BOS Jhb. No one at ABSA seems to be interested in helping us explain why or how this is possible. We can't reverse the transaction and everyone at ABSA seems to just want to pass the buck to someone else, even their legal department can't properly explain the reason for this! I want answers and NOW! Surely, this is illigal? We need this money back immediately. I've read we're not the first and only people this has happened too? This is theft!
