Advance Payment Issue - Need to Resolve Payments to Fraudulent Vendor

Good morning! I am hoping that I can get some help to resolve an issue that we have come across. We have advance payments that were created for vendors that proved to be fraudulent. The payments have already been made, but we know that there will be no parts received to close the loop. What would be the cleanest way to resolve our transactions in Epicor? We know that this is going to be a loss.

I did some research online and someone mentioned a Void Pre-Payment option but I do not see that on our menu.

Thanks very much for any suggestions.
