Okay thank you so much for responding. I was hoping this was just a big fake and a good hacker..everything about it seems fishy since it was done only over email. We even called a lawyer and they told us that they can’t take you to court over email.
Once a trademark is registered the brand owners can sue. They have screenshots as evidence and some even purchase an item from your store. If they frozen thousands of dollars then find an attorney that specialize in intellectual property if not let it go.
