[Payments/Purchases] Triple purchase and no access to Minecraft Java Edition

This is more of a payment issue, but I can't find where I should file this problem.

 

As described: I tried to buy Minecraft (three times), the process failed three times, and now I have three different charges on my account. I will provide extracts as needed, unless you redirect me to some other department.

 

What I want to happen: two of the payments should be returned, and my account (associated with my email veigabuenoender@gmail.com) should be created as expected.

Plus, there should be a more obvious way to contact help for non-game-related problems. FAQs are nice and all, but sometimes people have problems that can't be solved on their side...

 

As this pertains payment, I've marked this issue as private.

 

Thanks for any help or direction on this problem.
