Hey even aside from corruption, I believe what they're looking for (and why they want it as a PDF) is the embedded links. A lot of the times the seller and item links which would normally visit the item page are either not there or redirect to something else on a fake receipt. I've had this happen a few times and just sending them a PDF from a receipt with all correct links embedded worked really well, so perhaps that will work.

Although just to cut out the risk, as mothered said, just send it corrupted and persist. It shows some extra initiative that someone looking to make a quick buck probably not (even though they are) go for.
