If I join a private game in bnet, seeing someone muling or just standing there with stuff on ground and I would pick it up, it would be theft for me and I would feel myself as a thief. Bnet may allow this because of the non existent nettiquette there, we wont. Because it's a private game after all, it's super obvious for everyone to not pick things up without asking. How can it be not obvious to you? You don't seem like a naive person to me, so come on, you are not playing fair here and you know it.

In the end, it's not about the items in this case, you know we can refund them easily, it's about the behavior. You are punishing yourself with it and I don't know for what reason. I'd suggest you apologize for what you did, give the guy the stuff back, stop the unnecessary talk that is obviously on infant level and just go on.

You didn't know, it's OK, take what we tell you and we can forget about it, thanks.
