Typical telemarketing scam. They claim they have prizes then attempt to get your CC number to sell you hundreds to thousands of dollars worth of vitamins to qualify to receive your "free" prize. Hang up immediately, add number to your call reject list, and move on with life.
Same as above, all false claims on how they got my number by a caller with a poor (Indian-sounding) English accent , as neither I nor anyone I know filled out any type of coupon.
He identified the company as "Fiore life" and after going along with his routine, he tried to confirm an appointment time for me and "my significant other" to collect my prize at Fiore's offices in Las Vegas, as listed on their website on S. Las Vegas Blvd. I assume you get roped in to "experience" their sales presentation to become a member of their timeshare or travel services.
