Inexperience of

I recently had a bad experience buying a car and had to return the vehicle 4 days later. The deal was cancelled with the dealer and Standard Bank. I just called Standard Bank customer care (Vehicle Finance Dept). I am told that they cannot find me on the system. After 30 mins, they could not find me on the system. I just want to check if the deal has been cancelled and that no debit orders will go off my account.
