Called back, blocking i.d., and got recorded message "number not in use."  Some autodialing telemarketer or scam artist, who has many in-house phone #'s, some "identifiable," and most of them "not in use" or "disconnected" if you check.  From what I gather, these weasels simultaneously dial a lot of #'s, and pick-up the first one the rep. sees was personally answered, then ignore all unanswered ones and even some others where a "live" person has answered, but reps. are all on-line.  Bothersome [***] pestering everyone, and promoting something which no sane person would want, or is an outright scam.
