This is one is new - at least for me.

I got a phone call from someone claiming to notice that my google mybiz info
may not be accurate, and they wanted to know my hours to make adjustments on
their system.  I start talking.. but then the person claims that the connection
must be bad, can't hear me and instructs me to simply call back using a certain
number. Of course!
