Their support is truly worthless. I bought an add-on to a game, it downloaded to 99% and refused to finish. I mailed support, perhaps 2 weeks later I received a generic did you try to reboot your PC response. So I listed the 10 different (including and up to complicated) things I had tried up to then and mailed back. Another 2 weeks later I get another response along the lines of whether I've tried restarting my Steam client. After a 3rd round I just gave up. In the end it was a network issue on their side that auto-magically resolved itself (after 1.x months)
