Levelninehundred scammed me for my whip pure.

Hi, levelninehundred offered a lvl 3 with 15M on it for my lvl 74 whip pure. I gave him all recoveries and pass but he told me the pass wasnt right. Tho im sure i checked the pass before giving it to him. Recoveries were changed and he went offline. The msn log is 28.3 kb big so i cant upload it.. what do i do?
