What are your opinions on the trafford publishing company?

Trafford Publishing is owned by criminals: Author Solutions. I purchased a package and published a book with Trafford Publishing and after they sent me my free copies and were selling the book, I contacted them to ask about my royalty payments because I know the book was selling. They said, your book is on hold because you didn't paying the publishing fee in full, which I did. There is a higher-up and his name is Eugene Hopkins, this guy is the biggest criminal. I dealt with him before when I asked they switched my production consultant and when I contacted him to ask for help because I dealt with him before, Eugene Hopkins said he never spoke to me before. Does anybody know how I can sue them? How can they say your book is on hold when they already sent you some royalty payments?
