Ajio — Promotional gifts

Hello,
I got a call from a woman claiming to be from sales and promotional department of AJIO.
They literally use the links and offers from ajio which looks so legit!!
They asked me to place an order from the ajio app but do not pay from the app. Instead send screenshot of the cart and pay through imobile app. Instructed the process on call and gave bank details saying it’s a tie up bank account with the company and RBI. I paid 5000, and in return will receive any one gift selected from 5 options. (I selected laptop) .. later they asked to pay 12999 against GST to process further, when I denied, he threatened me saying if you don’t RBI and indian government will ruin my life and send notice at my doorstep. These people are using AJIO’s name and doing illegal things collecting money with tricks which looks so legitimate!!
Following are the bank details and contact number used by them!! You

I hope you take some serious action against this and save people’s hard earned money. I lost Rs. 5000. I need the refund!!
