It's Health First (Health Insurance) with some "tips"

she said her name was marybeth from some health insurance and asking for my dad...

They called me too and are asking for personal information. I think this is an attempt to steal your personal information (date of birth etc).

If it is really Health First - it's a dumb and unprofessional way to contact their customers.

Keeps calling and leaves no message. I don't pick up on phone numbers that I don't recognize. They're getting blocked.

they claim they are mary beth from health first but health first knows nothing abt it.
