Overpayment kept quiet

Hi. My house went on a auction on the 12 April 2020 in Pretoria. I spoke to the lady by the auction and they cancelled a amount on the costs. When they payment was made by the attorneys the incorrect amount was taken. I confronted the auctioneers and they said they will refund me. If I did not follow up on the account I would have lost almost R6000.00. If you deal with Rout-X, please confirm the payment amount. You never know what will happen to your hard earned money.
