Wesbank taking money that is not even owed to them.

My vehicle has been paid off but WesBank continues to take the full debit amount off of my account. This month they have caused my other debit orders to not go through due to insufficient funds. I hqve tried calling multiple times and I then get put through to customer service where I have been weiting for 41mins then again waited 27 mins and then again for 24mins. Every time the call just eventually drops.

I have sent emails and gotten no response except for the automatic reply. My credit score is now going to be affected because of this.
