Yesterday I got a call while I was at work, today it rang twice. I looked the number up and it says it's from out of Cooperstown, NY. I don't know who they are because I never answered, but they didn't leave a message either.
Has called me 16 times in 3 days and I'm blocking the number. Never leave a voicemail, and when I've paid attention they only ring 2 or 3 times before hanging up.
