Google says no free bumper case for My Nexus 4, even though the order page showed free bumper

I ordered a Black Nexus 4 in the Google Play store on June 1st. The order page clearly stated a free bumper case was included, but I did not receive it with my phone. Now Google customer support says I was ineligible for the free bumper because I placed my order 4 HOURS before it was "officially" available. They refuse to send me the bumper case unless I return the phone under "buyer's remorse" and REORDER the phone to get the free case. Buyer's remorse is right - I'll be returning the phone and they can keep it!
