I already asked him to refund my money - he is not responding to my emails.

Not sure whether you can file a complaint with paypal, when you send money under friends and family though.

Same here! This seller is a Scammer.
I bought a netflix account - he asked $5, First he sent me an account with invalid password, when i asked sent a different account, same story. Repeated the same 3rd time. Now he is not responding to any of my emails.
I didn't get to watch even a single movie.
Beware! He will ask you to paypal to a different email, via friends and family.
