Query: Thumbs Down on Thumbs Up

It's impossible to rate a product that was never received. I made the mistake of ordering this product (Murder She Wrote Seasons 3, 4, 5 & 7) from Thumbs Up, one of the vendors on Amazon's site. In an effort to rectify the situation, I have since emailed twice to Thumbs Up and received no response. I have filed for a refund through Amazon's Satisfaction Guarantee program. This was the first time and the last I'll order from Thumbs Up. Having said that, I have never had a problem with any other of the many DVD's purchased from Amazon or any other vendor from their site.
