The refund check was assigned to A/R when created.  A credit memo was also created and linked with the refund check, but that did nothing for the unapplied overpayments, so they are still showing as credits to the customer’s account. I've unlinked the Credit Memo from the check, but the check still is not appearing in the received payment screen. I need to correct the customer's account balance! 

Please HELP...Thanks!
