Received a from this #, it ring 3 time & hang. I phone back a few times & the line was busy.

Did not know who called, rang a few times and hang up. Caller ID shown "Unknown"

They've been calling all night, but I didn't answer, they just keep calling and calling!

Called on May5 20:41,  May 7 17:20,   May7 21:14   May 8 19.:28   May 9 16:19 and  May 9 17:29
Caller ID shown "Unknown", I did not pick up. So freaking annoying. My number is on "do not call list"

Boy, did they dial the wrong #! There is no way anyone in this house would support the PC party, ever.

No idea how they got my #.
