Been getting these calls for months.  Use to be a 480 number only, but now they have a 520 number also.  I get calls from both every day.  Do-not-call-list complaint does nothing.  I listened to the whole robocall this time and he asked me to press 1 if I wanted to participate.  Got a bad connection to a real person, who I asked to quit #$*# calling me.  She said yea sure, and hung up.
