Hello, I'm looking to see if anyone can help me with my problem. I was trying to set up a FaceIt account to play a 6V6 on TF2. Long story short, I sent a trade offer to one of my real life friends with about 90% of my TF2 items, and it said the trade was accepted, but he wasn't on his account at the time, and he doesn't have the items. Is there any possible way to undo this and get my stuff back, or at the very least talk to someone in Valve to fix this problem?
