Your rights in the US, EU and UK state you have 14 days to refund a digital product with no questions asked.
If you download, install or use the product via any means you waive this right.
If you bought the founders pack you a shit out of luck. Steam provided you the pack.
You accept there can be issues with digital services such as server issues or downtime.
You have used the pack so your rights state you aren’t entitled to the 14 day weekend.
For every bit of currency from the pack yiu have spent it goes against you.
You need to prove a substantial portion of the product is unplayable.

Who ever you paid the money to is responsible for the items you purchased.
