Cyber Crime Cell, Navi Mumbai — I'm complaining hacking of my Facebook and Instagram account

I was scrolling my Instagram a individual approached me and asked for help. Then said me that he/she required vote for some social media contest. He/she said that, " I will send you a link don't open that just take screenshot and send me. " But just after that my account was hacked and my verification mail id for password was also changed which has restricted me from changing the password.
