Help Me Please!

[Tubby_Tubbs]

It seems that I have been scammed. By someone who was apparently trading platinum. I was selling some eggs and, not knowing at the time that platinum CAN NOT be traded, I sold my 3 eggs to him. I realized by researching, tried to get a refund but he just avoided and un-friended me. What can i do now?
If anyone can help I would be grateful, and to whomever solves the problem, shall be rewarded.
I know it isn't much but I would appreciate anyone willing to help.

Details:
My Username: Tubbytubbs
Scammer's Username: Paopad (could've changed)
Things I Lost: Blgiht Egg, Dauphin Egg, Abigail Egg
Reward: Most likely egg (not Deary)

Thanks,
Tubbytubbs
