Who called from 5624486474

this number called. no msg. my number is unlisted.

Same as "roger".  They called, I let it go to our machine, and they left no message.  They disconnected as soon as the machine picked up.  Our number is unlisted too, also on "do not call" list.

This is a robocaller. DON NOT CALL LIST totally being violated. AND, my number is also unlisted.
