Caller fails to leave a message. Likely a scam.

Caller did not choose the option to bypass my phone call blocker so I don't know what they wanted. Presumably a robocall. Number now blocked permanently.

Another one of the 667-309=xxxx numbers that have been calling here over the past week or two.  A call back gets an extremely long message about their hours of business and on and on, but never identified who they were or what the call is about.  At the end of the message they say if you'd like a call back please leave your full name, address, phone number...I'm surprised they didn't ask for my birth date, social security number, and a credit card number as well.  Clearly a scam of some sort.  Another number from these lowlifes is now blocked forever!

No need, just block them and all their ilk.

Another spammer using a new number because they think they can get something. If you don't answer and don't call back, this low-life scum will dry up and die.  Also received a call from 667-401-6591 yesterday. Related?
