Truecaller

My cell phone number is listed in the National Do Not Call registry, so why do I keep getting annoying spam calls?  News flash: crooks don't obey laws.  Now I'm fighting back thanks to the Truecaller app which lets me know when reported spammer, like the one below, is calling.

Big shout out to my friend Jim N for this pearl!
