I have been defrauded.

I got a video on YouTube, as I was being told that if I want to do a channel for only 150 rupees, then I messaged on WhatsApp, after that US asked me to pay 150 rupees, then he said that I have increased my subscribe but put 349.5 ₹ drink, then I picked up the phone of us, then he said. That you have put 349 ₹ and maine 349.5 ₹ ki ki ki usne kha ki yeh youtube ka niyam hai ki na pe zaida na kaam maine phir 349.5 ₹ pay ker diye phir usne ne dab kaha kib249 ₹ aur pour maine kaha mujhe mere pesse return ker do us ne said ok phir usne tha ki sam 5 o'clock tak aa jayenge abhi phone block aur watchchat me bhi mera no. It has been blocked.
