I live in Toronto and received this call from St. Louis. No relatives or friends in the area and they simply hung up. A telephone scam for sure. Not bothering to answer again.
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.
