Unauthorised debiting of account

I called and sent an email with my statement attached on 11 June 2015 to cancel a revolving loan product but received no reply from Nomsa or anyone at Standard Bank. <br> <br> I told Nomsa that despite there being NO amount owed on this account since March - in fact an EXCESS of funds in CREDIT) Credit Life insurance has continued to debit the account each month!<br> <br> I will report Standard Bank to the banking ombudsman for this as it is not acceptable!!<br> <br> I want a reply to my email, an apology, a refund since the account has been in credit and I want the account CLOSED!
