called a while ago, didn't leave a message. ID said customer support. Anyone else?

CID shows as "Noritz America",  but I'm sure that is just a cover since Noritz is a legitimate company,  selling water heaters.
The Caller congratulated me for being selected for a VIP vacation from Hilton (or Sheraton).  When I declined,  he just hang up without a word.  I should have hang up right away...  No need to be polite to these people.

sales call for vacation club.
Very rude.

Received call, no one on the line.  Apparently a sales call

Hilton Vacation club, I listened and was interested. asked for money today... When I said I can't just decide for the family and give a CC over the phone they hung up. I have done these vacations before and have never been hung up on... I fell like it was a scam for a CC.
