Shocking service from ABSA Insurance

I have been with ABSA for years so the service I received has been shocking. I am looking at moving banks. I cancelled ABSA insurance because the monthly cost was 200% more expensive than other companies. The consultant phoned me and asked why I am cancelling. I told him and asked him on record if ABSA will be cancelling the debit order, he said yes mam don't worry. Well it has been 2 months of me going to the bank to cancel the debit order and reverse it and now THEY ARE CHARGING ME R40 A TRANSACTION FOR REVERSING THE DEBIT ORDER THAT THEY WERE SUPPOSE TO CANCEL. The service is shocking!!! And they can't tell me that the debit order won't go off again.
