I sell through a brand that I have included in the Amazon Brand Registry program. I got good sales figures and Chinese scammers immediately started to appear on my list. First 1, then 2, and now 12 sellers are on the list. My list price is 12.99 and I reduced my price to 9.99 because of these sellers, but the Chinese can lower the price to 2.99. I really can't believe this! Amazon needs to fix this immediately. Otherwise, sellers like me who want to do their job correctly will have to leave the platform.
Since you are in BR, consider at least trying this --
WHITELISTING
It seems clear that Amazon is only allowing MAJOR brands to 'whitelist' which sellers are authorized.
It was suggested by one of the long term experienced sellers on a different forum that the following has worked successfully in the past.
Have your attorney send a carefully worded Demand Letter (by Certified Mail) to Amazon’s "Office of the General Counsel".
These are the most recent addresses I could find for the legal beagles…………...

I would think that you would want to include appropriate paperwork showing ownership of the TM from the USPTO, proof of registration in Brand Registry, and, any links to cases and messages that show that SO FAR Amazon has refused to protect your brand.
Basically, you need to put Amazon on notice that you expect the protections promised by Brand Registry.
