Corporation Bank — Cheated of Rs.15000

There was this agency that conned me into paying them Rs.15000 to claim a refund and I was told that was because Corporate/Corporation bank accounts need a minimum of Rs.[protected] in order for the amount to be transferred. They told its necessary to generate a transaction ID on the basis of which they will rewire the amount into my account. I followed their steps as instructed, they told me to create a new account on the UPI, give it my name and transfer Rs.10 via it. Then, repeated the same process and told me to transfer Rs.15000. I stupidly did. And then, they told me the amount is hung on the server and they will do it with the current procedure and transaction will happen in an instant, for that, they asked to manage another Rs.25000 just for a while. DO NOT GET ON WITH SERVICES IF YOU HAVE LITTLE DETAIL ABOUT THE COMPANY!!!
