I lost my skin somehow?

Well, i am new and i wanted to sell my USP-S Dark Water on this site.
I created a listening, and it said the bot offered me a trade for my USP-S.
(I have a svreenshot if you need it).
But right after i accepted the trade, i went back on this website and it said there was an error. So i go to my account, then i went to “my listenings” and it said i never have listed anything. So i went to my STEAM inventory, and my skin is gone. So can I please have my skin back? Thank you!

I’m sorry to hear about this issue. If you haven’t done so already, please send Support a ticket with the screenshots so we can look further into this for you.

Samething happened to me! I have been waiting for three days but no one has responded to my ticket:(
