Make a handwritten receipt. Note in bold at the top it is a replacement receipt for the original receipt issued on XX date, receipt #xx

you don't need a new copy of the receipt...you have the original. Making a new receipt from the receipt book leaves you with 2 receipts which YOU don't need. They just need something to prove they paid.

As much as they wronged you in the past, you get no benefit by standing firm on making them pay...all it is doing it stretching this out and making you have to stand your ground for people who could care less. Be done with them. Make a written duplicate, put it in the mail and end contact.
