Reporting Slashz for his Giveaway

Scammer's profile link: http://www.sythe.org/members/401720-slashz.html
Explanation of the trade:

I won 2 times for the giveaway for Slashz; http://www.sythe.org/dice-competiti...-rs3-bonds-membership-07-gp-free-entries.html

Won a Bond, Rolled a 31: Page 35
Won 10m RS3 gp, Rolled a 2000: Page 38

How they scammed: It had been 3 days and he haven't been able to pay me. I noticed that whenever he logs on Sythe, he is just on for 1-5 minutes and he would message me if I want it now. What is the point of asking me if he isn't going to give me a reasonable amount of time to reply back? I tell him that I do but he isn't on whenever I am on or if he is on, I am at school.Is it possible if a staff member can get it for me?

Also, I give http://www.sythe.org/members/86467-lorenzo.html permission to get it for me or receiving it from a staff.

 

It's a giveaway.
He'll get to it eventually, it's only been a couple of days. If it becomes a week without payment repost this dispute.
