Amazon allowing counterfeit sales of my art??

I sell on Amazon a piece of unique and original art that is copyrighted. Often, copycats appear selling my design and I use the report infringement function to remove them. One week ago however, one of the counterfeit sellers issues a counter-claim stating I am mistaken in removing his ASINs. His name was listed in Chinese characters and his “address” was a string of letters. Amazon advised I needed to open a lawsuit in 10 days or else he would be allowed to relist the ASINs.

I hired a freelance lawyer to draft up the complaint and I filled out a civil summons. I went to the Superior courthouse’s clerks office today in Stamford and I was told I needed to first serve this mysterious person in China which seems complex, convoluted, expensive and a waste of time.

I wrote to Amazon pleading my case but I doubt they will care or assist. Does anyone have any experience similar to mine with a positive outcome? It seems like this person will be allowed to continue illegally selling my copyrighted artwork.
