The dude who called me had a thick accent and said he was an employee of Marriott, offering the 3 day/2 night + 2 roundtrip tickets to San Diego or Las Vegas for attending the 90 min. presentation in their new Draper, Utah location at 405 E. 12450 S.  Because it was Marriott, where we always try to stay when traveling, I agreed to go.  A woman then got on the phone (their "confirmation manager") and tried to get more info, which I didn't provide.  Thanks to everyone for posting this as a scam.

I just got a call from these people. I interrupted her opening speech about a getaway by asking “whom are you trying to reach?”
She said, “the owner of the phone”.
I said, “I am the owner of the phone. Whom are you trying to reach?”
She said she couldn’t disclose personal information.
I said, “I am on the national do-not-call list and you will be reported”.
She (rather quickly) said “thank you” and hung up.

Just got a call fr them twice this month now and both times she said she was fr Global Exchange and I asked what is that while interrupting her twice asking for my name.  Both times I informed her this number was on the national do not call list and both times she hung immediately

Received a call from this number less than an hour ago and she said she was from Global Exchange in Long Beach California. Well my phone clearly stated she was calling from San Francisco/Northern California using that number. I immediately called her a liar about her location and proceeded to hang up the phone. I seriously forgot that I should have waitied a few rings and the REAL number she was calling from would shoe up on my phone because of the App on my phone called "trapcall" which would unmask the phony number and expose the real one.

just received a phone call from this number regarding "free destination trip to vegas or SF".  where i told the person i spoke to no thank you, take my number off this list. the response was an F bomb, to which i just hung up.  Pretty sure it is a scam company or possibly a time share type thing, but who knows.
