Trademark Engine keeps sending me emails asking me to sign the same document over and over again. They then sent me an email stating that they received my signature and to ignore all emails about signing again. And that they will send me my filing receipt for my trademark I paid for. A month goes by and I get another email from them stating I need to sign again. When I informed them again I signed and provided them with their own email words stating they received my signature, they sent me a reply to sign again. It has been 3 months since I paid and they did not send me a filing receipt with the USPTO. I have asked for a refund or I will do a bank charge back. I should have used legalzoom.
