What is the electronic crime number to contact if the Facebook account is closed?

Some people impersonate a girl who is a friend on Facebook and ask you to message her on WhatsApp. Then they suggest using the Imo Camera app, and indeed, they appear on the camera and start masturbating. They ask you to show your naked body like hers and want to see you having sex with her on camera. She and her accomplices, who remain hidden, record you and also capture pages of your friends on Facebook and WhatsApp. They threaten to share the images with all your friends and upload them on YouTube. They demand money in exchange for deleting the photos and videos, starting a process of blackmail and threats.
