Oklute escort service - Asked money for providing service

I was searching a platform which can give girls escort and I found oklute. I got a contact number from oklute who send an escort girl. I had a talk and he provided me information and sent some images of the girl. After that he asked me to pay *** for booking confirmation. I paid the amount then he share an address of the hotel and told me to go there and sent him the photo once I reach. I did the same then he told me to confirm a booking, I have to pay the full amount which is **** rupees. I paid the amount then again he asked me to pay the security amount which is ****rs. As I don't have that much amount in my account so he asked me to pay the half and the other half he will arrange so I paid ****rs. Then he informed me that he mistakenly sent me * booking links, for me and for the girl. He told me to pay ****rs again for girl security deposit. I denied and request to sent me the whole refund as I don't want any service so he told me to pay the cancellation fees which is ****rs (**%) of the total amount. I denied and called him a scammer then he showed me his real face as threaten me.
