Proxibid Proxibid fraud! Internet

 I purchased several items for $700-$800. During the auction via live chat I questioned the specific auctioneer (Omega Auctions) regarding the authenticity. They replied that if they were not as represented they were returnable but shipping was on me. I was good with that. The items arrived and all were fake. For example, while they appeared to have petina, according to a local jeweler the watches all supposedly from late 1800's were cheap reproductions. Then the three supposedly authentic n**i knives all had "China" stamped on the blades. I called ahead to Omega, was told to return them, did so as advised, then via email and recorded voicemails (proof retained) confirmed that Omega returned the items to the original owner and got the money returned to them. Omega, advised me the money would be in my account within days. I have this via e-mail and voicemsil. . It's thee weeks later and I have yet to see a penny returned to me. The auctioneer (Omega) won't answer their phones. I reached out to Proxibid for help and was told...sorry, you're on your own! They have greater influence and leverage over these organizations but won't even try. Like other similar sites and administrators involved in such transactions by which they are paid, I feel Proxibid need to vet these orginzations better. Like eBay, PayPal, Amazon etc. they need to have recourse built into their agreements with these organizations when such circumstances exist. According to Proxibid, they do not. At this point, I haven't the merchandise nor the refund...I'm on my own!!!
