AVIS is a well-known car rental company, and I've used them before, thinking they should be fine. However, in late March, I rented a car at Los Angeles Airport and encountered an unprecedented situation. Arriving at the AVIS airport rental point around 3 PM, I saw a long queue at the counter, nearly extending out the door. After about an hour of waiting, I finally completed the paperwork. I thought I could just take the contract outside and pick up a car, but was told by the staff there that I needed to wait another 1-2 hours for the car. I was shocked and only then noticed many others waiting for cars. Eventually, I got the car after 6 PM. Not only was the pickup slow, but returning the car also had issues. About a week after returning the car, I found a $102 charge from AVIS on my credit card. Customer service said it was for refueling since the car was returned without a full tank. However, I clearly returned it with a full tank, which was checked by the staff at the return point. After providing evidence and having customer service contact AVIS, I finally got the $102 refunded to my credit card last week. Kudos to the rental service's customer support for their responsibility and efficiency.
