I just received an email from Hertz where they got me with the missing supercharger fees on one of my previous rentals. It appears they are going to get us with the missing supercharger fees. I guess I'll be insisting on an ICE car since I'm not getting free fuel anymore.
I received that also from my last one. The interesting thing was that my checkout receipt was $XX higher than my original check-in receipt that I get at the gate, but after the rental, I was charged the original amount. It wasn't until two months or so later, that I received the letter charging me for the difference. That was weird.
