Change banks

We’ve recently changed banks and along with that have changed where our credit card transactions flow to the new bank. We’ve changed our bank in company config. for credit card transactions, but now we have an adjustment that was done and applied a credit memo back to a credit card. The problem is in Epicor it put the $$$ back into our old bank account. Does anyone know where or how to change the default bank for these adjustments/apply credit memos?
