That's a bit rude. That guy was just doing his job.

Received a call from this number, I picked up, heard 2 beeps, then the call automatically ended.

Good one! He's probably still 'in a fog'.

The cell phone they reached is only the "car phone."  Nobody uses it and it's just a prepaid phone that sits around until it's needed for trips.  No way did anybody "do business" or anything else, as it's never answered.  Definitely a rip-off call.

ROBO-SCAM -- They called my cell phone with a recording that I had visited their website and won a gift card - please press 1 to claim your card or press 2 to be removed from our list.  I pressed 1.  When the guy came on the line and asked my name I blew a boat horn in his ear.  That gave me a great deal of satisfaction!

They called with some BS about "...a merchant you recently did business with..."...blah blah blah, something like that, but they couldn't tell me who the merchant was, even if I agreed to give them my info.  They were rude and hung up on me as soon as they realized I wasn't a sucker.

Its a 'rewards redemption' recording saying that you've recently visted a website (but don't say which one) and you're now entitled to a $100 gift card if you.....get the story?  Its a rip.
