A. It's the company's money not mine, so why should I care? And depending on how big the in-app purchase was, spending even more time on the ticket would cost more than undoing the refund would be worth.

E is for edgy anons from 4chan and most likely will get you in trouble in the real world (threatening a co-worker).

For digital products, it's quite common to have an internal policy of refunding with no question asked. It prevents chargebacks and is a good way to appease customers.

In those cases, it's still good to know if the user actually made the purchase and note it in a file associated with that customer so that in case of future support request that information is present and easy to see.

Without knowing details, it's hard to say, but my first thought is that support person x asked if the Custer received the purchase, not if a refund should be given.

Maybe the support team has training/instructions to always refund but maybe note that a user is potentially scamming. That way they can't strike twice. Or maybe they give different responses based on receipt.

I wouldn't assume they are trying to waste your time or disrespect you, but if you're curious about standard practices ask your boss if they know the procedure.

Asking nicely why he did that is not an option? Without assuming malice, which you seem to do. Might just have refunded to make the customer happy, which isn't unheard of.
