Escort Scam

I booked an escort for the traditional Rs 300 booking charge and when the time came, they told me that they were waiting in a car near my flat and the girl will come only after I paid the remaining Rs 200. But when I paid, they told me to pay the rest Rs 2500 which after a lot of discussion I paid but then they start saying there's Rs 5000 security deposit which they will refund which after a lot of discussion I also did. But then they start saying that as I made the girl wait, the girl is demanding more 5000. I told them I don't have that much and they then started to threaten me that if I didn't pay they will bring up the girls and make a mess in the place (I live in a residential area). I was forced to pay up. But then they didn't stop, they keep asking for more. At this point, I stopped and blocked them. Everytime the payment was settled, the girl started demanding more and then the dealers starts to threaten. Also everything was happening through call. I want to know if there is a way to make them caught with my anonymity staying intact.
