Greatly Increased Flurry of recent calls from dubious, Related Caller ID Business Names to my Private, Unlisted, Unpublished Residential Phone. I can’t demand they stop calling me because no sound/voice is on the other end to make this demand. I’ve been on the National DoNotCall List for Many Years. No Voice Mail Message, silence on the line when answered, hangups by calling party within 5 seconds without any voice or recording at the caller’s end. Not sure why the recent surge in calls has occurred – nothing has changed on my end. Pure Scum.
