No Idea who or why this number called +7 (0980986-96-9

I also just received a call from this number and they left no message. I did discover that 709 is the area code for Newfoudland and Labrador, Canada.

I think it's a scam. They called me today and an automated message said "We have a great special for you for being such a valued Costco member. Press 1 to receive this special" (or something like that)
Totally a scam...I've never had a Costco membership and this is a brand new phone # that no one has yet.

Same here. I missed the call and when I called the number it said the number I reached was not in service.
