After reading the above comments and having the same experience I blocked my number and called them back at 2:AM today and the robo machine answered with "Hello and thank you for calling. If you would like to be placed on the do not call list for the number that called you, please press 1 now" followed by dead silence for a few seconds and looped 3 times before it got annnoyed and said "thank you for calling" and hung up.
Why aren't we given a choice to report these numbers as spoofed scam calls ? None of the options for Call Type are illegal so they don't matter in which case what's the point in reporting the calls here ?
