National health organisation big cheat

Monday, 6th august 2012 I received a call from one santosh kumar of national health organisation offering health and medical - his no.8750554413. When I asked some questions he transferred the call to his superiod sikandar no.09711427810(personal and he can be called at any time for any assistance). He said we can get hospitalization and medical facilities across india for free. Sikandar directed me how to make credit card payment explaining step by step which I DID. He also said there are schemes going on that if booked for another a gift is assured and also for 5 bookings some philips product and 15 to 20 bookings LCD tv. Also mentioned they are the one who provides vaccination for polio at railway stations and house visits for polio vaccinations. Also they directed me to their website. All these things hooked me into believing them. I myself joined with family (4 people for two years costing 900) and another family of 4 members for one year costing 600. Altogether I paid through my hdfc credit card rs.11,500/-. Two days back a lady called me to confirm the address for sending me the card. Then I asked for some clarifications for buying medicine for that she asked for the name and address of the pharma company which I sent but no reply yet. They also gave me ID no. 9428 for me and for my friend 668. Any further details require, please let me know
