I received the worst car ever in HI this week.

Our flight was delayed and I was late for an appt. The line for the desk at the airport location was out the door. My name was on the board so I just went to my spot and left with the assigned vehicle. We saw all the rusted scrapes and scratches on the exterrior and had the agent at the gate scribble random notes and marks on the contract.

The car had not been cleaned from the last renter. It was covered in caked on mud and sand was everywhere. The Interior carpet was separating from the floorboards and it smelled bad. Yes, it was a Jeep but I had just dropped off the same vehicle in just fine condition on another Hawaiian island.

We were being hosted by some clients who drove most of the week but when it was my turn to drive, I was completely embarrassed as the seats and chassis squeaked and rattled. They could not believe this was an Avis rental and not "Cheapo Auto". Great!

I tried to call the local office to register a complaint and got a busy signal for hours. I called the 800# customer service. After a ridiculous negotiation, I was told the most they would do was a $30 credit ($400/5 day rental) but then he disconnected me and that offer was not reflected on my receipt on return of the car.

I am Avis Preferred and a regular customer that has never lodged such a complaint. What is the best avenue have this issue addressed?
