I think i was scammed by OneLazyNinja

Today i've found this forum and i wanted to sell my steam account. Someone was ofering to buy it. Despite he was a newcomer, me aswell, i went first and gave him the account.
Then he said that he sent payment, but i didn't receive any. After a while he said the transaction is PENDING because paypal needs to take money from his bank account then into my account. And after that he logged off of skype.
If this is true and it is PENDING how many days it will take ? And if not should i go to the steam support?
edit: I'm new to skype, but on some accounts i get offline, and on his account i get "This person has not shared their details with you". This means he deleted me and blocked ?
he is online on the forum and doesn't answer..

Unfortunately, it sounds like he scammed you. We cannot ban him based solely on your testimony though. Please provide evidence of the transaction between you two and proof that he scammed you.

 

just edited the 1st post..
i edited the pics where my e-mail is visible, but left his.. so everyone would know

 

so what happened?
i see him very online !

 

Cropped screenshots of the MSN window is not adequate proof. Please read the stickies in this section on how to properly gather evidence and put together a scam report, and then feel free to submit a new one with sufficient proof.

Thanks.
