A great 10-day travel in northeast USA

I followed the instructions to return the car and received a bill with no additional charges, but my credit card was repeatedly charged at midnight for two consecutive days without any explanation or invoice. I have no idea what the charges are for, and neither Hertz nor the car rental platform have responded after a week! It feels extremely risky to authorize my credit card to them! The car was in good condition, but how can this unauthorized charge issue be resolved?

Renting the car was convenient, but returning it was very inconvenient. Although we were told that we could return the car after working hours, the garage was closed, causing us significant trouble in the middle of the night. We had to pay for parking ourselves and wait until the next morning when the office opened to return the car. This was really unsatisfactory.

The tall African American guy was very nice, providing thoughtful advice and guidance.

Good

Had a bit of a wait picking up the car. It seems like I received an upgrade as the car was larger than what I had booked.

Easy to book but mobile app not working as well as desktop version.
