Since the claim was withdrawn prior to the 10th business day, I agree that provisional credit would not be required. Rather than waiting until the customer came in to sign a letter withdrawing the claim, from an audit standpoint, it is better practice to send the customer a letter at the time they orally communicate that they are withdrawing the claim.
Dear Customer, as a result of your withdrawal of a claim of an electronic funds transfer error, we are closing our investigation into your claim...
This provides a better paper trail demonstrating why provisional credit was not provided.
