I am afraid there is no way in hell you can get the items back. You see, since you simply gave this guy the items, there is nothing that anyone can do about it because it might as well have been a trade between friends, or simply a gift. Keep an eye on people that take advantage of your kindness and stay safe :)
So the guy took my trade id and made an account with ops skins bot name and send request from the opskins bot account it felt pretty normal as I was depositing skins to ops skins to verify that the skins are trade-able
