Which battery was fully charged? The Fob's? The 12-volt battery? The HV battery?
Sounds like the fob battery was dead, in which case you should have been able to start it by holding the fob near the start button (see your manual).
Make sure the "other" fob is not inside the car, or near it, as well. That can cause issues.
If all else fails you have a warranty.
Oh, welcome to the Forum here.
