Just another annoying something-or-other.  Caller ID says "Unknown Caller", but displays the number. Over the last 2 weeks, this number calls my home.  They let it ring 3 times and hang up. 45 seconds later they do the same thing, 45 seconds after the second call, they do the same.  Doesn't really bother me during the day time, but at night, it's annoying for sure.

Call asking about disability I say I am not on it and they hang up

Called, left no message.  Blocked.
