Absa are rogues

Absa Vehicle Finance has completely ****** me and are unresponsive to resolve the issue. I have paid up my vehicle finance amount owing, and they still deducted the amount from my account. They are unresponsive to resolve the issue and pay me back the amount in full plus interest. I would advise no one to ever take vehicle finance with this bank or deal with them in any way because their service is completely pathetic.
