Prestige Vacations Private Limited - Package not refund

I was called saying that I won a draw and to collect gift. But when I went there they kind of forced Me to take their holiday package for *****. But when I realized that the hotel and tariff list they are providing are literally the same even If you inquire that hotel in person so I see no benefit (zero benefit) in taking this membership. So I asked for the refund on the next day itself of My joining but they are saying they don't have any refund policy. I'm actually surprised why any company will not have refund and cancellation policy then I realised they are kind of interested only in taking money from the people as much as they can on the same day and later say they don't provide any refund!
