My complain against BigOption

I’m going to submit the internet crime complaint against binary options brokerage company “BigOption”.

Could you please recommend me the most relevant European financial markets’ regulators and authorities where I could submit a report about this binary options scam?

Optionally, please post FPA’s links where already discussed similar topics.

Any suggestions and links would be highly appreciated. Thanks in advance.
