can i please get refund?
Welcome to the PlayStation Community.
All sales from the PlayStation Store are considered final & generally no refunds are given, having said that on some occasions contacting customer service can yield a positive outcome, it's worth a try I suppose, but games are clearly marked as to which system they are for.
No one here can offer you a refund, but Sony's customer service number is at the bottom of this page under "contact us", try it, you never know.
Customer Service - 1-800-345-SONY (7669)
Available Mon to Fri From 8am - 8pm PST
