Wow..just now I got a call from 650 353 9154 with the same scenario. first name correct and the last name & industry wrong. not sure what they are up to!
Just had a call from 650-353-9154 caller asked for a past employee and I said that person doesn't work here any more. The caller asked my name and I said they just call me Mr. Toolbox and so should you. I hung up.
I keep getting calls from this number. I don't answer and they don't leave a voicemail. I called the number back and get a "This number has been disconnected."
