Fx wildcat warranty. Who, where why?

now that I have my new impact, I planned to send my wildcat in and I just realized that airguns of Arizona is no longer a Fx dealer. I bought it from them, had an overall bad experience, water under the bridge. 

So where do I send it now? And is my problem even going to get fixed? A few months ago it seemed to be cocking a little rough so I pulled the probe to inspect it and found the hammer was nicked up on the end and the bore it rides in was all scored. Since I didn't have a backup gun, I cleaned up the nicks on the hammer to prevent any more damage and reassembled it. It seems like its cocking better but it concerns me why it happened and if it will get fixed. 

Who is recommended here for warranty work? It was purchased 3/18
