This was the 4th or 5th time I was charged for gas when I returned the tank completely full. I've used Fox for more than 30 rentals over the years, but this was my very last. Not because of the fuel issue, they've gotten out of hand with the post-rental charges, and miscommunication. If you're going to, without notice, later charge my card for a slew of fees then at least be consistent. Sometimes I am charged fees and surcharges, sometimes I am not. Sometimes the return is fine, sometimes I am charged for non-existent damage. Get it together.
