Who called from 3018162424

Same here.  Hung up on answering machine.

Called cell phone and hung up when I answered.  The call came from a Kaiser Permanente regional center.

I am on a Kaiser-Permanente "reminder" list for a seminar (sales pitch) that I signed up for, and got a no-message call from that number. It is probably their areal outgoing call center.

The lady in the phone said she was from Kaiser. She called to tell me I needed to pay $497 I supposedly owed to kaiser . When I asked more info she sounded very confused and coul not give me accuaraye I formation about my visits and how she came up with that figure I owed
