Yallstock Yallstock @ eBay Thieves, cheats and liars Internet

I won a bid for an eBay auction item.  Yallstock then sent me a message saying I needed to send them $19.95 more for them to ship my item.  I had already paid the $20.99 requested in their eBay add for shipping plus the cost of the item I bid on and won for cheap.  I contacted eBay to complain about Yallstock's extortion attempt and the eBay Rep read the extortion message and said Yallstock was holding my item for ransom, this was not right and that eBay would investigate.  It has been 6 days since I won this auction and they have yet to ship although they did give me a tracking number, (PROBABLY BOGUS).   Also, Yallstock continuously engages in Shill bidding.  This means that they bid on their own auction items to elevate the price which leaves the buyer to bid above the artificially inflated bid in order to win the item.  Many of these Chinese eBay auction sellers do this same thing for electronics item auctions. 

These days I click the "Report this item" link very often.  I select "Listing practices"  next... "Fraudulent listing practices" and finally... "Seller is using other accounts to inflate item price".

Yallstock sells a ton of stuff on eBay so I would doubt eBay will do much of anything to correct this situation since eBay would be hurting their own bottom line by doing so.  It's all about the money!
