Brand restrictions on approved branded products.

Dear Fellow Sellers and Amazon Staff,

We’re seeking advice on a brand-level restriction issue we’re facing. Although we were approved to sell this branded product and fulfilled orders without issue, our listings were suddenly removed due to flagged supply chain authenticity.

Steps we’ve taken:

Sent a comprehensive appeal to pq-brand-remedy@amazon.com

Attached all relevant supporting docs (bank statement, EIN, both supplier invoices, proof of FBA delivery, etc.)

Contacted Account Health and Seller Support — both advised we wait, or contact Brand Registry again

Tried using the built-in appeal form, but it didn’t route to the appropriate team

Still no response. Is there a reliable way to escalate this further? Have any of you had success pushing a review through when standard channels failed?

Thanks in advance for any direction you can offer.
