Escort services Scam

I have contacted an escort agency during my visit to West Bengal.The agency guy asked me to pay advance of 1000.00 which I paid.Then he told me that he will inform the place and before entering the premises I have to pay more 4500.00 towards service charge.Once I paid 4500.00 again he asked me tonpay 10000.00 as caution money followed by another 10000.00 for coding charges which I have paid and they told me that these 20000.00 will be refunded once the service finished.Immediately again they asked me to pay 15000.00 more for police security which I denied to pay.But soon they threatened me that if I don't pay atleast 7500.00 more then they won't refund the 20000.00 so reluctantly I paid 7500.00 more with an intention to get back my hard earned money.Soon I paid 7500.00 again they told pay the rest 7500.00 or else not even a single rupee will be refunded. Now I am in a mental agony due to the financial loss so what should I do now?I have lodged a complaint in the cyber crime cell of Home Deptt. Govt of india.is there any chance to get my money back? Is there any law to prevent these fraudsters to trap anyone else?
