Club Aliva — fake company

I was approached by a sales person in manali last year, who then took me to golden tulip hotel (Mall road-manali) and introduced me to 'club aliva' representatives.
The sales pitch involved the benefits i will get if i take membership and also was given a voucher with a free holiday.

I took 5 year membership package and paid 80, 000 inr upfront.

Since then no communication from club aliva yet. They promised to send emails/postal mails etc, but nothing was received.

No one is now responding to my calls/emails.

Can you help?
