He said he is leaving for vacation and you refused paypal and said you would give him the time to make the cash back.
Nike, buy the gp from a gold seller and give it to him.
I'm assuming if you ran servergeeks vps you left your osbot info on there and he used it to scam someone. I would suggest you change your password, but again you are responsible for your account. You have to pay it back or you will be banned.
I can confirm I sold him this account, I gave him no information except to set the email which was unset when he received it. I had the account for 3 years.
