I would ask him to sign and document. Then mail a letter stating his choice to withdraw; be sure to keep a copy for your records. Reg E is a very consumer friendly regulation, but nowhere is it stated that a customer cannot withdraw a dispute. We have had similar circumstances when a customer has disputed, viewed ATM images, then withdrew because they wanted to protect the son/daughter/grandchild/etc. In this case we close the dispute without credit. Or if provisional credit had already been provided, we reverse the credit and then close.
