Today I received a communication from GamersGate:
Sorry for a long reply. There seems to be an issue with the third part indeed, and it is great that you contacted the publishers on it. We do not have much to suggest now since we tried to resolve the issue. As you can see the game is not sold for the moment so we are waiting for the resolution from Telltale. But I can also issue a refund in blue coins so you can later on buy any game for the same amount using them without having the troubles of using a card - instantly and anytime you like.
More information can be found here
!! Please Note: We are very sorry for the late reply. We have found out that we had a problem with the email server and a lot of tickets and replies were never delivered or received.
The problems are hopefully solved now, but there is a lot of catching up to do."
Michael, is there anything you can do? I'm not after a refund, I want the hot game! Can those of us who purchased Episode 3 from GamersGate provide proof of purchase and then download it direct from Telltale?
I look forward to your advice.
