There's an Enbridge scam making its rounds here in Ontario. They call you to inform you that you owe them money. I wouldn't be surprised if this caller is also a scammer. Whatever you do, do not volunteer any information whatsoever.
Starting last night I get a phone call from this number every 2h or so. It rings two times and it closes. When I call back it sounds like a fax machine.
They've been calling here every hour or so all afternoon - at least four times so far. I refuse to answer the phone if I don't recognize the number, and I have better things to do with my time than be harassed by idiots.
