when i click on "check bid results" it says "bidder information does not match"

 

It's just poorly worded. When you "bid" on an item, the game collects everyone that tapped bid in the allotted time and essentially raffles the purchasing rights to one of them. If you weren't chosen, you get the "information doesn't match" error, which just means you weren't the chosen one. If the chosen one declines, it goes into instant purchase mode and you can maybe get lucky there.

Korlitek even if pressed the bid and then it gives you bidder info not available and the item still in the market for 6 min !?

Windwanker,

This is because whoever won the right to buy after the bid ended never ended up buying it. Unfortunately you don't actually need to have the necessary amount of silver to initiate a bid. Anyone can do it. But if you can't afford a bid you've won, it will sit there for a set amount of time before becoming up for grabs. So if you see that happen... It's best to just keep refreshing. Chances are a lot of people are doing the same but it can't hurt to try. :)
