A call came in from the above number and no one was on the line when I answered. The phone showed "Natl Wire Cable" as the caller. I called National Wire and Cable in Los Angeles, they are not making these calls. It is against the telemarketing law in Maryland to call and leave dead air for more than a certain time and then call back repeatedly. I suspect it is an autodialer
They called repeatedly today after the third time I picked up. The guy asked me "for my friendship". I then told him I did not like Humans so I would not be any help.
