Class D Audio Brand does not honor warranty---AVOID!!

About a year and a half ago, I purchased a budget two channel class d amp from the internet company with the same name, "Class D Audio", and wanted to warn others of my bad experience. 

After about year of using the amp, I started to get static and other nasty sounds coming from my speakers. After checking and confirming that is was the amp and not any other components, I sent it back for repair under warranty. The owner, Tom, was my contact person, as well as the person that checked it out.

Tom said he found nothing wrong with it after thoroughly looking it over and assured me it was fine. After about three weeks he returned it, but it wasn't fixed. In fact, it was probably worse. After again checking all my equipment out, I was certain that the amp was defective.

I contacted Tom about the problem, asking for some guidance about what to do next, but he initially didn't return my emails. After over two weeks he finally emailed me and again insisted that the amp checked out fine. 
I said that I wanted to send it back, but Tom again took a long time to get back. In fact I had to send him several emails. When he did, he said he had a family problem, and that he was having a difficult time returning emails. I told Tom I was sorry for his troubles and to take a LITTLE TIME if he needed it, but emphasized that I needed this fixed asap. (It had been months now since it was fully functional.)

That was the last I heard from Tom. I emailed him a couple of times, with no response, so I've given up. He stated that the warranty is three years, but he he avoids customers like the plague if they have any problems.

His website is still up, so I don't think he's out of business.
Anyone have any idea what's going on,or had a similar experience?
This guy is a deadbeat as far as I'm concerned.
