Great Holiday Club — Looks like fraud company

We have been approached by great holiday club members in Goa. After their brief and tour around a hotel facility. we have been asked to pay 50000 which was paid. we were informed that we can pay remaining 50000 after 1st stay. However, Chetan their agent is not responding to my msgs and neither is there any reply to my mails from company's official mail. Iam attaching photo of the agent chetan.
