Account deactivated/suspended an hour after being active.

Hi guys, so started my amazon fba journey a few months ago. it took me a 2 months to find a few products that dont require approval and are not restricted that are still profitable. I decided to list some Stop smoking Products. Gums sprays patches etc. the day after My products reached the FC and the 8 SKUs were active for an hour, made 3 sales and my account got deactivated. They deactivated my account and sent me an account health notification saying they need the invoice for 3 Asins in my inventory. 2 asins were inactive and i had no invoice or purchase order for them but 1 of the asins was
part of my order from the supplier in the uk.
the supplier is not affiliated with the brand, he has an amazon uk store and ebay and other eccomerce websites but also sells products in wholesale on the side.
I sent them the invoices and an appeal for the other 2 Asins since i dont inted on selling them. but it was rejected and my account is still deactivated.
Any help would go a long way, I dont know what to do. I have $5k invested in those products and no back up plan.
