Unanswered call to my mobile phone, no message. Strange, I seem to be getting a lot of calls from locksmiths (that's what this number says it is on Google). I swear I already blocked him.
It doesn't seem to help that I never answer unknown calls (they don't even ring on my home or mobile phones), block them, and report each one to the FTC. I still get one or more of these a day.
