Royals Club International - False Promises and misleading customers in the name of holiday package

On *rd October ****, there was a seminar of Royals club international going on in Calangute Goa. A person from Royals club international stopped us on the road, he said Royals Club celebrating its anniversary and giving free vouchers to couples. He gave me a voucher and asked me to scratch which he said I won some exciting gift, and for that, we have to attend a workshop of ** minutes which was arranged at Hotel Goan Heritage, Calangute, Goa, where they trapped me and my family by promising good accommodations in * or *-star hotel in the budget price of ** years of tenure, but we refused the offer. they had put huge pressure on us by extending the conversation for two and half hours(between ** pm to *:** pm).
Accidentally we visited that seminar and their employees shared fake information about their club. They manipulated and gave me Gold membership for ** years, and for that, I paid them **,*** Indian rupees. A few days ago, while I was investigating Royal Club International and their hotels, I found that they are doing fraud and misleading the customers. I sent multiple emails to avail hotel accommodation from the membership but they are not responding to my emails and also not providing the service. While I was talking to their employee during the seminar, she told me that I can revoke my membership in the next ** days without any deductions. I want to get a full refund from them. Please help me.
