What legal action can be taken against recovery of money?

I was going through a channel that claims to help people by making them money. As a student in need, I asked for their assistance. They provided screenshots of payments made to various individuals, and I invested ₹5,000 to receive ₹20,000, as per their rules. However, they subsequently asked me to pay a GST amount of ₹9,240.07. I mistakenly paid ₹9,240, and then they insisted I pay the same amount again. They then requested a fast transaction fee of ₹24,999, which I struggled to arrange. In addition, I paid ₹15,759, hoping they would compensate me for the amounts I mistakenly transferred. They refused to return my money and blocked me after I repeatedly pleaded for help. I am in a dire situation and urgently seek your assistance. Please help me.
