It was my mistake that caused this bug in the first place and I felt kinda responsible ;)

Oh, and
NOT iN ;)

Considering that I'm on team responsible for getting games running (preferably before release >.>), my experience with GOG Support is that whenever something is broken / missing or needs to be added, a Support minion comes to me and gives me a death stare unless it is solved quickly ;)

I rarely contact any Customer Support. After all, trying to solve problems on my own is something that gave me a place in Tech team ;)

I have one positive story with Origin Support:
I pre-ordered Dragon Age Inquisition in Origin Store and once pre-load started I noticed that only Polish localization files are present. A bit of research shown that pre-ordering from Poland landed me a Polish-only version with no easy way to switch (it was possible with some hacking involved but then I would have to remember that with each consequent patch).

So I contacted customer support (chose UK, as I heard that PL one isn't reliable) and flat out requested a refund so I can buy a 'proper' version elsewhere. I was offered a version switch instead - they removed previous one from my account and added English in its place.

That was mighty nice and hassle-free (took under 10min) :)
