Sigh... It was about the Hatchet Quarry DLC. It was up on the TS website store, I searched for it on steam and could not find it. I did send a ticket to DTG, but did not receive a response and time was running out (sale). So I went digging into the steam database and there I found it. I made a post on the steam forum with a link, so people who would also want it could buy it too.
4 days later, yesterday (so after sales end) I finally got a response from DTG saying that the Hatchet Quarry DLC was only available in the US
So I posted that response in mentioned steam topic, stating that while I've had positive and satisfactory results from DTG support in the past, this was clearly a response from someone that doesn't know what she was talking about. I also suggested that perhaps DTG should monitor their support a bit more. What I most certainly did not do was call anyone names or anything.
So ye, then the whole topic got deleted. I was really upset about it yesterday. But today I'm like 'whatever'...
(and if I should have also kept my mouth shut here, just delete it. I wanted to just let it go but since people are asking...)
