I've received several calls from this number but have never answered it.  They have never left a voice mail message either.  Today I figured to call them back and I got a recording that said something like, "You have recently visited one of our webpages and have one a $100 gift card good at stores like Walmart, etc."  

Okay, so if I did "visit", how did they get my unlisted cell phone.  I NEVER make that available to random webpages I visit.  If a website wants a phone number, I tend to give them an old one from my childhood days, but never a true number to ME personally.  So that alone tells me this is a robo call and I never visited any dang page of theirs.  Just put them on ignore and silence their ring.

Did not answer & no message was left... I'm sure it's bogus!

got a call from this number on an unlisted burner phone from boost mobile 2 days after activation.  it only rang for half a ring and then disconnected.

Hopefully, it's not a shell number for a current scam that directs your call to an international number (based in Caribbean) that results in outrageous fees.  Here's a recent article about it:

You might want to contact your phone carrier to check for any additional long distance charges.

Best advice - If you don't know the number, don't call it back.  If it's important, they will call back.

Just got a call that rang for half a ring then disconnected.  Looked it up and found these reports - so assuming it's a RoboCall.  Also on do not call list and unlisted.  Not going to call back - thanks for posting it up, folks!
