iPDA DELAYING CREDIT CLEARANCE WITH NO REFUND

The iPDA has received money back from a creditor on 08.08.2020 for paying it into a closed account. We were handed over to attorneys by the creditor. We need to pay the attorneys but the iPDA cannot trace or refund our money so we can pay the attorneys. I am constantly following up and getting the same response for 4 months now. This is the only payment delaying our credit clearance.
