********* Billing of Account

I opened my Russells account last year February and paid it off this year early Jan but debit order still went off even though my account was closed. I called the JD Group's financial department and they confirmed that my account has been settled and is showing a balance of 0.00. Now in Feb I get an email saying my account has a balance of R306.07 and that they will be debiting it at the end of the month.

Called their finance department once again and they told me that they can see that the account has been closed but they can't give me an answer as to why I was debited.

The JD Group finance people are chancers.
