Tate Publishing Failed to deliver books after being paid Mustang Oklahoma

I engaged Tate Publishing to publish my manuscript.  They did edit and set-up the book, and they provided limited marketing services.  When I ordered and paid for 20 copies to provide to reviewers, they promised to deliver in a few days.  Over three months later, no books and no responses to my numerous inquiries.  As far as responding to my complaints, they've fallen off the face of the Earth.  Additionally, despite their promises (and they claim to be a Christiasn inspired company) there are no copies of my book available to be bought on Amazon.
