Got this number calling me as well, didn't answer because it's a number I don't recognize. They didn't leave a message, surprise surprise. I'm also getting a lot of calls from an unknown number, that's how it appears on the caller ID. It's pretty much harassment at this point because they call multiple times a day, and will call repeatedly. I downloaded an app with the hopes that it will reject and/or block such calls, fingers crossed it works...so tired of this b.s.  Apparently the Do Not Call List is a total joke.
