My seller account has been deactivated for several months due to authenticity concerns related to a specific ASIN. That ASIN was also flagged in a separate performance notification, and I participated in an Amazon video call for inventory verification. Following that call, Amazon requested additional documentation, which I provided, and the inventory hold was subsequently lifted.

However, despite submitting extensive supply chain evidence—including confirmation from my supplier that the inventory was sourced legitimately, along with documentation from my supplier proving they sourced the product directly from the manufacturer—my account remains deactivated.

This prolonged deactivation has resulted in significant financial losses, both from lost revenue and the forced removal of inventory from FBA. Every appeal I’ve submitted has been rejected with the same response:

"You have not sent us sufficient information that we previously requested from you to address our concerns with your account."

I have carefully reviewed all past performance notifications and, to the best of my knowledge, have provided all requested documentation to verify the authenticity of my inventory.

At this point, I’m unsure how to proceed. Has anyone successfully resolved a similar issue? Are there any additional steps I can take to escalate this matter or get further clarification from Amazon?

Any guidance would be greatly appreciated. Thank you!
