Not in but +1 for the giveaway. I've had nothing but great results with GOG's support and think it is better than any other gaming site in the industry that I've dealt with. They're polite and friendly and usually respond in less than 1 business day unless they're swamped during a sales promo or something and then usually within 2 days max. The odd support query might get lost from time to time and someone might have a bad experience but such are rare occurances which are exceptions and not normal by any stretch.
Any time I've had a problem with a specific game and reported it, they've responded with a suggestion to try or an outright solution and without exception so far within 1-3 mails usually they've nailed a solution that works, even for some of the most obscure problems.
I've had purchases not go through properly with games missing from my order and they've apologized for the error and explained the glitch then gifted me the missing games no charge, I've been offered free games a few other times for relatively minor inconveniences too. They also have a great sense of humour too and not some static corporate suit and tie feeling. I appreciate that.
I've seen some people report having bad experiences over time too, but what I've notices is that often people jump to negative conclusions about GOG too fast and don't give them a chance at all then curse them into the ground. GOG is just a company like any and ran by humans and they can sometimes make mistakes or get overloaded or similar too. It has been my personal experience that they truly want to serve their customers and do the best they can to make people happy to shop here and that if people make _that_ their default assumption when they have a problem, then communicate the problem through support politely and with respect and patience then wait at least until the next business day or two in Poland timezone, that GOG will resolve their issue, and if for some reason they don't - persistent patience with them will pay off in the end. I think most people who have bad experiences largely create the bad experience themselves out of anger and frustration and then bad hostile communication.
So I for one am also very happy about GOG's support and trust them more than any other online places I shop. The second best customer support experience I've had is shopping online at
http://www.staples.ca for office supplies etc. A lot of companies could learn a thing or two about customer support from GOG.com and Staples. :)
Anyhow +1 for the giveaway!
