First I got a silent or dropped call from this number, then it tried again, and I got a robo-sales message, one of the standard pitches which starts, "The FBI reports there is a home break-in every...." I immediately hung up. I don't give my 646 phone number out very often, so I wonder if they're just randomly robo-dialing numbers in the area.
Same here they just started calling me today. I have had my phone number for six years and never had this number show up before. They do not leave a message. I blocked their number.
