Explanation of the trade: My Rs3 account for his 300m Rs3
How they scammed: He said he will buy my Rs3 account for 300m Rs3 but only had 148m at that time and he said he will give me 70m the next day and his friend would give me 82m soon. we used a MM and everything went fine and the next day he gave me another 70m. The next day i saw he deleted me from skype and Rs. I really dont understand why he would give me 70m and then not pay the other 82m :/.

I posted my skype in my thread so he didnt send me a message on sythe at all. he asked for a qeustlist in my thread and i told him that through pm.

His friend saying he would give me the other 80m: http://gyazo.com/502319ff264904282043e52f5688c0ca

He deleted me off skype because he claimed his skype got "hacked" but not his rs account, he also deleted me on rs

Skype confirmed ^

Looks like there's possibly more to the story, but all I can see now is that he isn't paying you, banned.
