This call came in on my land line at 0419 hours on 01.18.17. I'm up at that hour but that's beside the point. I did answer but there was no response to my brief and unladylike tirade. This follows a call from a, supposed, Chicago, IL number at 2347 hours yesterday. It's bad enough these cretins interfere with people's routines in the first place but to do so well outside the limits of appropriate telecommunication hours is uncivilized. This is MY telephone, the service for which I pay; it is unacceptable for unauthorized persons to use it at will.
