Scammed 600m OSRS

Scammer's profile link: Lacoz
Explanation of the trade: So I went on scythe like I usually do to sell my gold and I find it very trustworthy until today I got scammed. This person post on buying osrs gold for $0.88-$0.92 per million in osrs gold. Buying 07 Gold / Best Rates and Fast [No Fees][0.88$/m - 0.92$/m]
I am very disappointed and it all happen when I tried to contact him through skype and he messaged me back. I was checking to see if he was still buying osrs gold and he said he was, so we went through the whole process talking on skype saying that 600m in osrs gold for $535.00 since out of everyone he was giving the highest pay as of that. I trusted him after he showed me his history of paypal, his ID, and e-mail. I unfortunately lost his ID picture since he removed it and the picture of him removing message will be all there in imgur.
How they scammed:He scammed me by telling me that I should trade everything first to him and he will pay me later through paypal at first I was hesitant about it since 600m osrs gold is a lot. After he showed me some proof I was willing to give it a try and then after the whole transaction has been processed of me giving him the 600m osrs cash he started saying if I wanted to sell more. After that message that gave me a bad sign that he was already trying to take more from me and then I was clearly telling him that no I am good with selling only 600m. He was like okay then ask for my email and I gave him it to him and he said he was having issue with his bank account. And I was to give 1 to 2hrs so he can fix the issues. It only has been about an hour and a half, but I scrolled up to see that he removed some of his verification messages, so right there and then it was for sure a scam. I still have all his information and going to post it here.

Hey Champ thanks for helping me out. At this point I do not know what I can do to get what I have lost back.

 

Awaiting his response, hang tight. If he does not respond, he will be banned.
