Received a call from 305-563-9744 notifying me that I had won a free vacation from some survey in a shopping mall (which I never do) and that I only needed to come with identification and a utility bill in order to receive the prize. I think they may be posing as or have set up a bogus travel agency inside an actual hotel, as they gave me an address which seemed to be an actual hotel. I can provide it if needed, but left it out in case it does belong to an actual travel agency. They claimed to be part of a company called Holidays Network Group.
Number not in service
Company exists and is well known. Might be impersonating them though. relevant news link https://www.eturbonews.com/158341/holidays-network-group-chosen-expand-sunset-world-resorts-vacation-experiences
Contact the company via http://www.holidaysnetworkgroup.com/ and try to verify.
