Moment ago I downloaded Plain Sight game from Gamersgate summer sale, and few minutes later made a few tweets.
Check the below discussion (click the image)
Basically: I made a comment about corrupted download file (at 11:20). 11 minutes later (11:31) gamersgate replies to me that they want to help me get it working. And a minute later (11:32) they give me idea of redownloading the whole thing. Few minutes later (11:35) I got the thing working.
If customer service is about following people who talk about your game… you certainly are doing something very right.
