Explanation of the trade:He opened a ticket on my server, he wanted an ironman but I didn't have it available, so he told me to train one for him. We agreed on a price and that he would pay after I completed the service. I delayed the service by 27 days due to an earthquake that happened in my country, and university and many things accumulated, and I finished it two weeks ago and he still hasn't paid me. He only covered the first 3 bonds, I covered the others due to the delay.

How they scammed:He provided the Jagex Launcher login which doesn't appear in the ticket because he deleted it, but you can see there that he was giving me the codes so I could log into the Jagex Launcher.
