Finer Details Mopar Customer Service Issue

Last Summer 2014, I bought an reconditioned 070 fan clutch from Finer Details at the Carlisle Chrysler Nationals.
When I returned home, I discovered the part was defective and sent it back to Finer Details a month later for a warranty replacement. Finally, in March, I was promised a replacement, but it wasn't sent.
I have, since then, tried numerous times to get a replacement part from Finer Details or my money back. My e-mails are being ignored and my calls are not returned. Since a year has gone by, I have now purchased a replacement part, so all I would like to do now is get my money back. Any suggestions?

Have you been talking to Ken Mosier?

Ken,is the person avoiding my calls

They will be at the Nationals in Ohio if you are going...

It would seem you are too small a fish for them to be bothered with.
There is no excuse for any business to ignore emails and phone calls on a product quality issue.

They obviously could care less about you or their reputation.
