I think you would be better off phoning PayPal about the latest refund. If your account is relatively new, or you haven't made very many purchases, the case and refund might have flagged your account due to a high percentage of transaction issues. (eg if you've only made 5 purchases, 1 resulting in a refund and the other a case, that would automatically raise a flag for 40% of transactions made - as it's often automated, so not the result of a person reviewing your account activity and making a decision, it will be much better to phone them and get - or give - clarification of the specific circumstances).

The seller of the game would have been given 10 days to respond, so it seems likely the refund will be processed within a couple of days.
