Twisted Terror Convention

I signed up with Twisted Terror Convention to be a Featured Artist at the event. I paid $50 for a table and was supposed to be guaranteed a spot and to be able to appear at the event. I signed in February 2013 for the event which was on March 29 and 30th 2014. I promoted the convention and even had the convention organizors on my radio show. When I signed they didn't announce me like the other guests. Also they never put my name or picture on any promotional material, which is not the standard of the industry. At horror conventions around America artis that pay for their tables are promoted and posted on the website as a guest. I was not. They put me is a separate section of the website by myself. Then on January first I got a PDF letter from the organizer, Aaron Dodge: Twisted Terror Productions Email: aaron@***.com P.O. Box 785. Lathrop CA 95330 Dear William Pattison, aka Eric Morse, We regret to inform you that we will be cancelling your Artist contract with us. Unfortunately, your attendance conflicts with some of our current Celebrity guests. Be on the lookout for you $50.00 deposit. We will make it out to Jeanette L. Thompson, unless you need it made out to someone else. This was a Team decision, so please stop all emails to Dorine. We have made this decision and we are not turning back. Our number one priority is our Celebrity guests and making sure that their comfort level is at 100%. We will be removing you from our website this week. So they broke and cancelled my contract because a couple of the "celebrity" guests didn't personally like me. This is outrageous. Now it will be hard for me to get into another convention because this makes me look like I did something wrong when I didn't. This ruins my reputation as an artist. The people are crooks and scam artists. They used me for a year to promote their event then tossed me like garbage.
