I keep on trying to purchase Divinity 2, and every single time, it says: "YOUR PAYMENT'S STATUS COULD NOT BE VERIFIED DUE TO TEMPORARY TECHNICAL ISSUES", indicating the problem is on their end. I really want the game, and have tried probably 15 times now with different cards and no success. Anyone have a fix?

Tried contacting GOG's support?

Were these different cards issued by different banks? If not, try contacting your bank as well.

Same game, same problem. I am trying to solve it with waiting - for now.

Interesting - I'm having the exact same problem trying to purchase the same game: DOS 2.
I've tried 2 cards.

Did waiting work?
I have read that letting support know about it is a good idea, but I can't seem to find any way of contacting support :-)

You mean you didn't see the big "SUPPORT"-button at the top of every page, you didn't hover your mouse over it, didn't chose "Orders and payments" as topic, didn't read through the information on the following page and in case that didn't clear things up you also didn't click on "CONTACT US" to get to the support contact form?
