Bought an 840 ring on the Mobile AH, only for it to become 810 in game.

How to Unlock and Kill Secret Boss Endgineer Omegaplugg and Get the Vial of Green Goo ToySame as title. I bought Sameed's Vision Ring on the Mobile AH for 25k. It was definitely appearing as 840 ilvl and had the stats of the other 840 examples, but was 5k cheaper. The 810 versions sell for about 7k. Now that I'm looking at it in game, it's scaled down to 810. It's no longer an upgrade for me, and I can't resell it without being down 18k~ After doing some googling I found this thread http://us.battle.net/forums/en/wow/topic/20748947603 Plenty of people experiencing the same thing. People saying GMs are telling them there's nothing they can do. I've posted a ticket but came here for ideas and to see if anyone else has encountered this? submitted...
