Holiday Kraft Pvt. Ltd - Cancellation of membership from Club Jiva

This happened in Matheran when myself along with wife visited for vacation. We have been duped by the Club Jiva Holiday Kraft Pvt Lyd- ** Level-*, Dewan Center, S.V. Road, Jogeshwari ( W) Mumbai - ******. They have forced us to sign the contract and later on when I find out in the websites I came to know it is a fraud company. I told them I want to cancel the agreement which I can do without one week of time at the sign of the agreement. I have written many emails and called up them. Nobody is responding and answering my calls. Please help for the cancellation of my agreement and I have told my Citibank card services to stop the EMI payment.
