Overpaid Account

Good day. I have been calling Standard bank to find out about my settlement amount for my car with no success . My calls have been transferred from one department to another.I used the amount on the statment I had only to find that it's old.can someone call me and send me my latest settlement amount and I need my refund processed ASAP as the statement I used was for October last year which I only realised after payment. Can someone please contact me to sort this out.
