Amazon Authenticity Complaint – Fight It or Take the Hit?

I recently received a product authenticity complaint on one of my ASINs, which has been marked as High Impact. As a result, my Account Health Rating dropped from 252 to 244, and Amazon has removed the listing.

Amazon has given me two options:

1. Acknowledge the violation, agree to never sell this item again, and take a hit on my account.
2. Submit evidence to prove the product’s authenticity.

The issue is that while I know the item is 100% authentic, I don’t have the necessary paperwork to submit because I don’t buy it directly from the manufacturer. I’ve been considering creating an invoice that shows I purchased it from a “supplier,” but I’m unsure of the risks. If Amazon finds out the invoice isn’t legitimate, how would that affect my account?

Would it be better to just acknowledge the violation and move on? Also, if I do acknowledge it, will my Account Health Rating continue to drop?

Would appreciate any advice from those who have dealt with a similar situation!
