Shows on caller ID as Unavailable. Does not leave message. Call area code originates from Toronto Canada. Do not know anyone in Canada nor do business with anyone in Canada. As long as they are 'Unavailable', so am I. Also get random calls from 416-422-0158 as well with the same ID -'Unavailable' with no message left.
I got a call today from that number asking to participate in a grocery survey. She had an obvious Canadian accent, seemed pleasant, and hung up quickly when I said "no thanks."
