Money refund for online purchased game (ARK bundle)

This morning I downloaded the ARK bundle on my Xbox one... However... After a few hours the game chrashes and every progress is lost. So you need to start all over again. This happened 5 times now so im done.. I want my money back.

How do i do this? just canceling the PayPal payment doesn't seem to be the most preferable option. I tried to find a button (refund, roll back or whatever) in my account details. Couldn't find it.

Searched the xbox connection options and got stuck in an endless spiral of pages that refer to each other but don't provide the option to talk to a real person (not very customer friendly).

Really hope that someone can help me because im getting pretty frustrated at the moment...
