Refund update
I contacted Xsolla support and this is their first response:
I had already submitted my request using that form. So I don't know why they asked me to do it again?
The next day this is their response:
So am I going to get a refund or not? Who issues them? Xsolla or game support? Whoever that is.
Backers do not pay a subscription during the beta. The amount of DAC which is part of the pledge package and actually is what you paid for (game time in advance) will not start to be used until "release"
