Briefly explain: Well Duly all of a sudden started saying that im a scammer he said the following "Such a noob trying to get my ip off Skype haha. Too bad I never logged it as I know capitals don't count on username. Have fun with ur ban xoxo" i really dont know what he is talking about im kinda lost
How they scammed: He told me to do his dungeoneering from lvl 70-82 in 4 days and that he would pay me after i finish it , i didnt even start working cuz i went to eat.
Proof that you were not talking to an impostor: i have the pm's on forum and on skype .
Screenshot's:






I still have no idea what i did , i just told him that i am going to go eat i came back and i saw a pm on my account on sythe . So thats why im reporting this to be sure because im lost , i did nothing to the guy i just logged in and told him that the account worked and logged out and went to eat as you can see the screen shot above.Could someone clear this up for me :huh:
