Who called from 5610000000

Caller said he was from Obama campaign. Told him to lose my number and hung up.

I am getting several calls per day from this number 561-000-0000!  Have no clue who it is.   Do you know how I can stop them from calling me?

This number called 3 times today. The first 2 times I missed the call. Before the third time I had entered the number in my phone as a Unwanted number and added it on my Rejected list. So the third time they called I didnt hear the ring and it went straight to the voicemail. The message was a very busy background, then a man laughing and then he hung up.

Started calling @ 7:00am and then hangs up when you answer.  Repeated calls

First call at 7:28 am. Are they serious? No one on the line. 8-/ So sick of these kind of calls.
