At the counter, I was asked if I would return the car with a full tank. I said yes, but they still charged me extra for fuel when I returned the car. They also added towing insurance without my consent, resulting in an additional $42.50 charge. I contacted the rental company, but they gave the same explanation, saying there was nothing they could do. However, after my daughter, who speaks good English, called them, they quickly canceled the charges. I've encountered this issue three times, and each time I had to resolve it myself because the rental company was essentially powerless.
