Accidentally blocked my friend and I want to gift him :c

Hey there. This might as well belong in another board topic (or in a support card) but I figured a post like this wouldn't fit anywhere else. If you wish for me to ask my request to someone more able, then please say so. So I've been meaning to gift my friend a skin, as we've been friends a while, and he wants it. Who am I to deny? It's the holidays, after all. But it turns out I couldn't, because about 4 days back I accidentally clicked "block friend" when I actually wanted to spectate one of his games. It seems like a far cry, I know, considering how different they look and all, but I kinda forgot where the "spectate game" option was and I just clicked the first thing I saw... bad habit :L So if possible, could I get some kind of "pass" that would allow me to gift this guy?
