Cheating

Good evening sir,.. My name is pramila from Bangalore. Me and my husband cheated by country vacations Company.. they told us they ll provide​ membership card valid for 30 years , we can stay in their property all over India and worldwide for 1 week per year. and many more promises like we can play games over there without any extra charges. We can resale the membership card for the same or higher value in future, by looking all these we found it exciting and took the membership by paying 2,55,000rs by credit card payment(HDFC bank and HSBC bank). After an hour we found out country vacations is fraud company. Many unsatisfactory cases we found through the internet. We mailed the details to the HDFC bank and HSBC bank to revert back the transaction. They replied back saying we have return back all the products/service taken from country vacations then only we can revert the transaction, we contacted country vacations to cancel the membership ,they replied saying it ll take 4 months for that , it's been already 5 months still they are not responding. We contacted country vacations office several times. They are not responding.. After mailing them to cancel membership also Country vacations asking us to pay annual maintenance fee of 12500rs.. Please guide us to cancel this agreement with country vacations
