Good evening.
Unfortunately there is very little you can do, as the steam community market rules on transactions are quite clear.

How can I reverse or cancel a completed Community Market transaction and/or get a refund?​

All purchases are final – you will not have any right to a refund or a reversal of any Community Market transaction once it is completed.​

This may be to much for you to bear, but it is impossible to retrieve your item via Steam after someone buys it

WE can speak with the guy , buyer . He is Russian.

Not a scam.

Market sales are all final, steam support wont do much sadly, however if that russian is a good guy he will work something out with you, but keep in mind he dosn´t have to in any case.

It sucks did that myself ealier not nearly as expensive item but i know how you feel.

I feel for you buddy, one expensive mis-click

Chalk it down to experience and move on.

Yeah, your "classes" of life, are paid per incident....

The Person Who Brought My Hat has Blocked me, he don't want to speak with me and he never speak with me, I wanted only to ask him if he wants to give me back my Unusual hat, because the price he have payed for my Hat is not FAIR. There is so hard to have an UNUSUAL Hat this days , Steam must do something about this things.
I fell so bad , When i added my hat to steam market i never used ',' to tag my price. I don't know how ',' was there, is so strange.

I am aware of that CHiDvD, but in steams eyes and SR eyes, his moral compass may be a bit wrong, however the fault is on you for not double checking, it sucks it really sucks no doubt, but nothing any of us can do besides being against his choice of ignoring you fully.

Steam sales via market is final in every aspect so nothing to do, perhaps if you are lucky a SR mod will try and talk with the guy but since he hasnt really dont anything wrong besides finding a amazing deal on the market i doubt that is even possible.
