At Los Angeles Airport, I was inexplicably charged an additional $30 for roadside assistance despite clearly requesting no additional services. They also did not specifically inform me about this charge. I mentioned that I might return the car two hours later than scheduled, and the staff assured me that extending the return time to 4 PM would be fine with no extra cost. However, when I returned the car near San Francisco, I was charged over $40 extra for returning late. I called AVIS to inquire, but they said there was nothing they could do since I had signed without reading the details. Originally, the rental cost was around $80, but I ended up being charged over $70 more, almost doubling the price. This experience was extremely disappointing and felt deliberately deceptive. This is not my first time renting from AVIS, but the experience was so poor that it merits a very negative review.
