Called me telling me I won a million dollars. When I told them I wasn't interested they tried to "confirm" my info to complete the so called registration. I prompty hung up without giving them any info.

Repeated Robo-calls, promises to remove my number from their call list.   Calls continue every two weeks...  unsolicited, unwanted, harrassing calls...

Calls almost daily. I am not answering.

I received back to back calls from this number, no message was left.

This number called me today, 4/13/2016, a total of 4 times in a span of 3 minutes while I was at work.
The distraction was caught by my boss who promptly gave me a warning regarding the use of my cell phone and checking my phone too often and it being a nuisance to clients and vendors.
No message left by caller, but the sense of urgency worried me until I checked the number online and see it is most likely linked to a scammer. Don't bother picking up, even if they call you repeatedly within a short amount of time; it's NOT an urgent or emergency call.
