I’m the lawful owner of -----COSMETICS, trademark #------, as documented by USPTO records. By law, the Brand Registry must be associated with my account. However, the trademark is enrolled under an account that I can’t access because the individual has passed away. WHAT TO DO HELP ME

I have applied for the trade mark registry in USPTO and got the serial number on the USPTO website. The website indicates the Trademark status as "LIVE". But in Amazon's brand registry the serial number is not verifiable.

Many hurdles

Error 5461 - Resolved

Error 8572 - Resolved

I've provided everything - personal identification, ABN number , GS1 membership certificate, Trademarking confirmation, Documents from my white label company (that arranged the manufacturing), Signed declaration saying I'm the brand owner and I take full responsibility.

And yet Amazon support are telling me "Upon checking, we are unable to identify that you are the brand owner for VEGA"

Please help! I don't know what else to provide to prove that I'm the owner of my own brand!!
