Errr...

I've never owned a playstation, let alone used their website.

I also received an email 10 minutes before saying '$20 has been added to your wallet' - but no information where the funds came from, so I don't know which bank/card to check!

A small dump of information if someone doesn't mind running a few checks?

I'd guess it's a legitimate account, funded by someone using their own credit card, but they have mis-typed their email address and you are getting the emails rather than them

Edited to add, what I said only makes sense if you and they have the same name. Which is possible, if you have similar email addresses.

I guess it could be ID theft, using your identity to set up a credit card account (in dollars?) and buy playstation games, but it seems weird - rather low value items
