Was downgraded by Hertz even though I have AMEX Platinum.
In meantime I booked two cars with Avis.
Sent email to Hertz as no one to talk with on the many options on the phone. About 10 days later I received
a congratulations email that I was Pres. Circle. - quite insulting rather than apology for the downgrade. At
least I saved $20 with Avis.
