Answered call and did'nt say anything, when a recording started I presses the # button 3 times and kept repeating the 3 # presses after a wait of asecond between the # presses, caller disconneted.

STOP YOUR CALL..NOT INTERESTED..EVERYDAY ...HORRIBLE

Called, no VM.  No ringtone so I was not bothered, but like to post here to help others if I can.  

Went straight to my YouMail message which puts them on hold with smooth jazz and insulting comments...love it!  One easy way to fight back at these idiots.

Daily calls from 202-350-3913. No VM. How to get rid of them?

It depends on what type of phone you have.  If a smartphone, get a free call block app.  If a plain cellphone save the contact with Z Scammer and set the ringtone to none and missed call to none and voicemail to none (if available).  If a home phone see if your phone company has call block or buy a cordless phone that has call block (Uniden and Panasonic both have models with this feature) or get an external call blocker like a Digitone Call Blocker or a Pro Call Blocker.

Political calls are not covered by the DNC rules and they seldom honor your request to not call you.
