I am a preferred member for over 10 years, but lately Avis customer service been so bad. I returned the car at 10:00am and the agent couldn't send me the receipt. I called customer service and the rental agreement wasn't closed, and he couldn't close it for some stupid reasons.
I travel for work and rent a car every week, but never again with Avis. They are still charging me for the day and the car was already returned. Be careful when renting with Avis, check your bill, watch the gas charge even after you fill the car up. They are cheaters and want to steal from you in any way.
