Winners are not responding HELP PLEASE!!!!

wait?
for a week and then you can ask for re-roll because they don't respond

Each of them have their email address listed. Request they accept your friend request on Steam to get their prize.

and in case you win a game and not give him who created this?
have a week?

Send them an email telling to add you. If they don't respond, wait one week (5 days more) and request a re-roll.

Ty guys for your help !!!! i'm gonna send them an email right now

If it's been 7 days, (particularly in the case of the dude who has blocked you), I'd get the giveaways re-rolled.

As others have suggested, you could try emailing them, but it's not up to you to chase down the winners beyond adding them on Steam. You've done your part, and personally if somebody blocked me I wouldn't waste any more effort on them.

that's why I don't create giveaways with less than $30.01 CV

Also, "if" the guy that blocked you did it without you ever actually chatting with him first, don't take it personal. Some people really have issues with random friend requests. Rude is rude, but no need to take it personal if it wasn't. Who knows.. could have been a psychotic parental unit too. ;)

If you added them and they don't respond to it it's their own problem. Wait 7 days and reroll.

you can send the gifts to their email address.

Ok so i gave 1 gift to one of the guys but it didn't count on Value...i have the same value like before...why??

Ask for a reroll. Simply sending them may not result in them flagging your giveaway as being recieved and you've got 2 blemishes on your account AND you're out of two games.

When someone wins, you can see the email address. That's how you contact people. Steam is NOT email, nor facebook. You want to contact someone, use email.

I had a similar issue where the winner never responded to my email, finally after 5 days I left a note on his profile and he responded right away.

Also regarding the winner that blocked you, you should check their profile to see if they've been on steamgifts recently. There's no way they could miss that green banner, they can clearly see the giveaway creator. If so, it's safe to say they probably don't care for the win and I would ask for a re-roll

You should check the winners profile. Those people like me who block random invites usually have a line about posting in the comment section before adding them somewhere on the profile. Anyway, maybe use another account (for the winner who blocked you) and put a line about them winning your giveaway and to unblock your main, if possible.

As for the other one, if seven days have passed with no response, you can probably ask for a re-roll.
