Need guidance

Along with many sellers , On 24th June , we received a notification from amazon that we are restricted to sell around 30 brands (small - medium sized brands) we have been selling for past 4 years. Right now we have 7 brands’ inventory stranded (49 listings) on our account , with no ‘apply to sell’ option .

-We do wholesale, sourcing directly from brands / authorized distributors

-We have LOAs and permission to sell on amazon from brand

-Brands are not that active on amazon and do not assign roles in brand registry to sellers. They are saying LOA will serve the purpose.

-We have confirmed from brands , there is not any kind of restriction from their side.

-Amazon gave us email to contact, we sent several emails but have not seen any response.

-Amazon is telling us to wait and delay the removal date , hoping for apply to sell option to appear.

What should we do now?

Has any one got some progress on this ?

Our account is healthy and active.

Major inventory is in stranded .

We have all documentation available

Invoice , LOA, Transaction details , POD etc

Is this USA? What categories are affected?
