Disappointed

I request a settlement letter from wesbank. I received the letter and all was good. I then sold my car and the dealership that bought the vehicle payed the settlement. I can see the payment reflected in my bank account but they still deducted the monthly fee. I am severely disappointed and unhappy with them. I sent an email to get information to what happened and to ask them to return my money but nothing has happened. I would not suggest wesbank to any of my friends to finance a vehicle
