So I get a twitter code from one of the contests yesterday.... and it doesn't work. Twitter wont let me reply since I can only reply to followers ~sigh~. So, I twitter to GoG that it doesn't work, no response. You guys are busy, I get that, but how do I properly report that ? I did try an email to support here, but no luck as well, maybe it takes a while with all thats going on.

Just wait a bit, and I'm sure they'll get back to you.

If not, prod them again in a couple of days.
