Is there any agency where you can submit complaint about online game on facebook who tookmy money because facebook is just resubmitting the issue back to the game and i am not getting any answers?

Facebook does not have anything to do with the games itself on the platform. You will need to submit a complaint to the game company. If you can tell us the name of the company, we can get you the details to write to them. The company will have to give you the money back. If they don't, you can submit a complaint to the BBB.
