The refund policy for the PlayStation Store was recently updated, but while it is nice to finally have refund options in place - where before refunds were largely unavailable unless mandated by local law - they're incredibly limiting. With the exception of subscription-based services like PlayStation Plus, digital products cannot be refunded once you download, stream, or play them. Additionally, refunds will be credited to your PlayStation Store wallet, not whatever card or account you used to make the original payment.
Further restrictions apply to games. You may only request a refund within 14 days of purchase, and again, only if you haven't downloaded the game yet. This time limit is absolute, but in the case of "faulty" content, you may be able to swing a refund after playing the game. These cases are rare, however, and require more than a few bugs or just a straight-up bad game.
Pre-ordered games follow similar rules. If you pre-order more than 14 days before a game's release date, you can refund anytime before the release of that product. If you pre-order within 14 days of release, you'll only have 14 days to claim a refund. So, if you pre-order 11 days before release, you'll have until three days after release to get a refund. The full policy adds that "you may have additional refund rights under applicable local law for pre-order purchases if the release date changes."
Subscriptions like PlayStation Plus and PlayStation Vue, meanwhile, may be refunded at any time, but only partially. Your refund will be based on "how much you have used the service. For example, if you buy a PlayStationTM Plus 12-Month Membership and request a refund seven days after the purchase date, the refund amount may be reduced to reflect any use of the subscription, such as playing online, downloading monthly games, using cloud storage, etc."
It's hard to estimate how much subscription refunds will be docked without seeing a real-world scenario, but considering the example given uses a seven-day activation window to explain a reduced refund on a 12-month subscription - and given Sony's stringent refund history - we can imagine the math won't be lenient.
"If you purchase a subscription service from PlayStation Store, you are purchasing an ongoing subscription with recurring fees that will continue until you cancel it," the policy adds. "While you can cancel a subscription service at any time, the service continues to the end of that billing period. Cancellation or turning off your auto-renewal will stop future payments of the subscription fees but, beyond the initial 14-day cancellation period, you will not receive a refund for payments already made."
Oh, and one last thing: you can't cancel or refund an ID change. So, choose your new name wisely.
