Deactiveted account

My account was deactivated two months ago due to Section 3, related to a product I sold in May. I haven't sold this product since then. I’ve provided all the requested documents and submitted five appeals, all of which were declined. Do you have any advice? Is there anyone here who can help me?

Today, Amazon informed me that they can’t verify the invoice because it doesn’t include a tracking number. However, invoices are usually generated after a sale, and the tracking number is added only when the product is shipped. So, it doesn’t make sense to require it on the invoice itself.

Additionally, the product that caused my account deactivation is no longer available on my supplier's website, so Amazon can't verify it there either.
