Called again around 7:30 last night when I wasn't home. Despite both versions of the number being blocked, it rang thru anyway. Obviously a "spoofed" number (a fake number displays--you don't get to see the real number). All I know to do now is just ignore 'em.
called twice more. Hang up after 5 rings. Caller id has been: "United Breast C" or "8506010014". I think they are also calling using 850-542-8779; it also comes back as a scam cancer charity
