Need advice for a Product Authenticity Complaint!

Hi everyone.

I'm looking for some advice on what to do about a product authenticity complaint for a product that I no longer sell and deleted the listing months ago. When I click the violation on the account health dashboard it says "no sales in the last 12 months". It says the listing (which doesn't exist) will remain deactivated until the issue is resolved, and if it is not resolved within 90 days then my stock (which also doesn't exist) will be destroyed at my expense.

The product was genuine and listing is deleted as I have no plans to relist this product in the future so I see no need to accept the violation or submit an appeal.

What should I do? Are there any consequences for ignoring the violation for a listing that doesn't exist?

TIA
