This sucks. Are they charging your credit card after you supposedly closed the rental?
I have now ended up being give a car with 3/4 gas labeled as full. The 1st time I ate it and didn't realize until I had left LGA and was already on the highway. The 2nd time I went back in and the guy updated the paperwork to 6/8 on the Out. But the agent checking me in didn't label anything on the Return, the receipt just said "/8"
