Who and why are you calling me.?

Why are you calling me this late, do you people sleep?

Hostile call made by this number

When the number is dialed the message says the subscriber is not available or has  traveled outside the coverage area.  Now what legitimate phone number gives an answer like that?! The number has been blocked.  I'm sure whoever this is has many more numbers to use and will continue to bother and annoy people throughout the country.
