VAF department should be fired

Standard Bank VAF needs to catch a wake up! I’ve struggled to settle my loan since 29th June. Now the loan is paid in full and because they’re incapable of working without client supervision I’ve been debited once again for the car payment and get advised by customer support via email to phone them to tell they haven’t cleared the account. WHY?!?!?!? I sit on the phone for hours every time waiting for someone to answer and run up my phone bills so that they can be told again they haven’t done their job. Don’t you baffoons get a salary?????
