Scammed by [email protected]

Hi, i just bought an account called Dragonpkz238 On runescape from a guy called Colton Williams - Skype name:Katanuu msn: [email protected]
He has TRYED to scam alot of people now, but failed. but he scammed me first of all i bought the pure level 73 off him for 40$ and then placed 100mill rs cash onto it from my main which cost me: 80$ i was playing happily on the account, after i logged off thee password hadd been changed. he is still advertising to sell the account now, so his game is that he sells the account, hacks it back, and scames another person who buys it.Secondly i would like to say it is illegal to scam a peersons In real life Cash. i dont know how loseing 110$ just from him is going to be resolved, but i want to know some way i can either get that account back, or the 40$ cash i sent to him over payapl iv been searching butt have found nothing. i dont know what to do as i cannot get the account back from jagex as it is illegal to buy / sell rs gold and accounts.
Please help. Thankyou.
