Skokka — fake registration

I had a posted a advertisement on skokka.in under adult meeting category in mumbai on 18th november 2018, following which i got a call from [protected] a guy claiming that he's from skokka.in and that they have a portal where in paying a registration fees of 3700 we get a six months access to a dating site.
He mentioned that once the payment is done the login details will be sent immediately within 5 mins. Following which he gave me the bank details which had the company name, which i found to be genuine as no body can open a current account without supporting documents if it's a company account. Details below

So i transfer the amount of 3700 though imps from my personal bank on the 18th night at around 10pm approx after which he stopped receiving the calls. I thought since it was 10pm they would have closed down. And again on the 19th morning he did not pick up the calls, and later after trying a lot of times he again sent me a whatsapp message stating i should pay a further of 2842 to verify the location of the device and that the 2842 would be refunded back in 10 mins. Once this amount was transferred, my mobile number was blocked. And he's been in accessable
