2 phone calls from this number   they hang up

this number 1-301-994-3379 called my phone number on june 7 2017 .I got message manager but there was no message left. I got to the point when I get the calls I am expecting I turn off my phone & message manager take over .This has got so bad it's so annoying it make me curse every one of them who won't get a real job in a world so rich with such idle nutbags..

Had this number phone me a few times, and just spoke with a gentleman from same number now.  He claims he was "from windows about my computer".  Uh huh.  I laughed and said oh because they make house calls now?  He didn't understand why I didn't trust him, but he refused to give me his name and number so I could verify him!  Total scam.

message left on answering device:  (Teenage girl voice) "Hullo...........Hullo?..........Hullo....."  then hung-up.  Sounded like caller was using speaker phone, other voices and sounds in background.
