Nestaway Technologies — Money looters

I booked a bed through Nestaway, first they showed that to block a bed you need to pay only 1300 but when I tried to do that they asked to me the payment of 2 months rent and Nestaway charges i.e. total of around 16K instead of 1300.
Again they asked to pay 2K for rent and later again they are asking to pay another 2K for some security deposit whereas almost 17K are already paid without stepping foot in the house yet.
