<human>: Condense the text into a few key points

So, this happened today - and yeah, this is a throwaway account.

In Sydney, we have a car sharing company called Hertz 24x7. The cars are parked at different locations in the city and it isn't manned by any one. You get a code via text and you enter the code on the car to open it. One of the requirements is that when we return the car to the hub, if the fuel is less than 25%, you need to refuel the car using a credit card that's inside the car. If you don't, you are fined.

I used the car yesterday to run some errands and parked the car at it's slot. Today, I re-hired the car to go to work in the morning and when I picked up the car, the fuel was almost empty. I was pissed! I called the customer care and complained against the previous driver who was discourteous enough to not fill the tank and now I had to do it. I was insistent that the other driver get a fine.

The customer service agent enters some keys on her computer and then tells me that no one had used the car from the time I parked it yesterday till I picked it up today. And since I had called and informed them, I - being the previous driver - will now get a fine added to my bill.
<bot>: Used Share car. Forgot to refuel. Picked up car today. Saw that the fuel was empty and complained. Got myself a fine since no one else used the car between my uses.
