I just had the same thing happen to me. I looked and looked, then I finally just called the place I rented from. They said it was due at the time of the reservation. I then asked if they could adjust it to the actual pick-up time because I rented it with the expectation of having it for a complete 24hrs. They were really nice, said no problem, and adjusted it while I was on the phone with them. Then I asked for an email confirmation. I ran into traffic and was actually late turning it in by about 30 mins. I was not charged an extra day. Call the local office where you picked it up. They will probably adjust it for you. Good Luck. :)
