Every time I try to contact GOG I get no response. Most recently I tried to contact them regarding possible account fraud. Haven't heard a word. Maybe this post will prick their ears a litte?

Nah they rarely respond to posts on the forums (these days). Send them a few more emails, and bug them on Twitter to get them to reply to your email.

Also remember that GOG does not usually work on weekends, so if you sent them a message after close of business on Friday (their time, not yours, they are in Poland), you might not get a response until at least Monday at the earliest, probably Tuesday (24-48 hours response time, after receipt of message).
