Same here. But I am registered with the do not call thing.... I know they keep moving, and using spoofed numbers.... I think they are the same group anyway, and as these unwanted calls have been going around for years, I always file complaints. Mainly because it's a cell phone...and I HATE being disturbed. Not that I think the gvt ppl with do anything, but a least I did my part.
They are simply spoofing the phone #prefix to match the number they are calling. I got robocalled today to my 340 prefix cell number. it disconnected as soon as I answered.
