Yep happening to me too, they call and hang up right away!

Called, rang twice and hung up. No message.

I called it back from my office phone and it said that I recently visited one of their websites and qualify for a $100 rebate gift card.  I pressed the number to talk to someone and I asked how I would have earned it.  He said I am a frequent shopper at some retail store.  

I didn't give him my name and instead I said THANK YOU and hung up.  I don't know if it is legit or not, but like my daddy always told me - if it sounds too good to be true, it probably is!

Called my Google Voice # & hung up, didn't leave a message.

Just called my cell phone, rang for a few seconds and then hung up. No message 1/17/15.
