same here, a friend told me to check my game inventory and his was in there, mine is not, and also I check inbox, spam and trash not there.

6 days since I opened the ticket, they said they will investigate, still nothing. GOG support slow or incompetent, I think I'll avoid them in the future. :(

I have signed-up on Nov. 14, 2014.Through daily login this site i've finished collecting stamps on Nov. 20, 2014 but till today no e-mail recieved me for the key. What is going wrong with gog.com ? How long we must waiting for response?

+1, I have the same trouble.

tap tap tap..... nope, not yet.... tap tap tap

Theoretically we could all download a torrent of Witcher 2 gog version and we'd not be breaking any law - if we did in fact get all 7 stamps.

GOG surely wil deliver. We just have to wait

I contacted GOG through their contact button and it has been almost a week with no response from them other than their automated response.
Honestly from my experience thus far they don't care about Customers with Freebie issues.

What else can I do but waiting? Contact with support? Checked. Any response? Yeah, right...

I've been waiting for like a week or two : \ still nothing in my mail.

Im waiting too, ive sent a msg to gog but no response..

Be sure to follow the advice given by one of the GOG staff in this thread, when contacting support: http://www.gog.com/forum/the_witcher_2/the_witcher_2_email_never_come/post112

Thanks, mate. Just received my codes.
