I got a call from this number on 2/10/16. No message was left. Someone with the same number called again today (5/9/16), but they left a message this time. I had won a free cruise (yeah, right), but I would need to answer a few questions in a survey. The voice said, "Let's get started! Would you vote for Donald Trump for President?" I didn't respond, and the call ended.
call my cell phone at least 3 times a week, sometimes multiple times on the same day. I do not give out my cell phone number except to family and a hand full of close friends. I have blocked, but continue to call.
