I got repeated calls from this number, all hang ups on the machine. Today I picked it up and it was a political pollster, the rudest I've ever encountered. After fielding about five minutes of questions the questioning turned incredibly one-sided against a Democratic candidate. When I asked them why the "poll" was biased they just kept talking, and ignored my request to stop.
Calls after 9 pm with great frequency. Robo call--when the number is called back, message kicks in saying that the person as this number has not got a mailbox set up yet.
