I have phoned to paypal, the guy told me they proctect buyers only for goods not for digital/numerical things.
He understood what i explained to him and told me to do a chargeback.
That's what i gonna do to get my money back.
He also told me they gonna check his paypal account to see if they gonna ban him or not.
I don't know if he scammed other people using paypal or not.
I hope this bastard will be banned.
