Sault Ste Marie, Ontario, Canada is what showed up on called ID. Never leave a voicemail calls allot! Whenever I answer this no one is there or it is a scammer. I've tried calling back sometimes too and it's a click or dead air or a scammer. I am registered on donotcall.gov but I guess that doesn't work
