Club Factory — got looted

A few days ago i received a call from club factory branch located in pune, that i have won a lucky draw and i have won a cash prize of worth 12 lakh rupees and that i had to only pay 7000 as gst. I had to provide my account no. And aadhar card no. I transferred the 7000 rupees.
But they demanded an amount of 12500 as my account was savings account.
After that no money was credited to my account and i had lost a huge sum of money too. This sort of fraud has happened. I complained once before too but no action had been taken.
