After trying out the demo of Pro Evolution Soccer 2013 (and liking it), I have accidentally purchased the PSP version of the full game, unaware that the full PS3 game wasn't available for purchase on PSN.
Please assist in refunding -- I do not need the PSP version of PES2013.
Welcome to the PlayStation Community.
You'll have to contact Sony customer support if you want to request a refund, they cannot be requested here through these Forums.
Just so you know all sales from the PlayStation Store are usually considered final & no refunds are given, but it's worth asking.
The number can be found at the bottom left of the page under 'contacting support'.
