Disrespectful pick up

I had three significant issues during the car rental process that I am very dissatisfied with.
First: The car provided did not match my reservation. When booking, I specifically chose a compact car for easier driving within the ancient city. However, upon pickup, I was given a tall SUV, which I was not comfortable driving due to my familiarity with smaller cars. The rental company had no other options available, leaving me with the choice to either accept the SUV or cancel the reservation.
Second: The rental company claimed there was a compact Nissan car available at their Avignon branch and reserved it for me. As a result, I altered my travel plans last minute and drove for two and a half hours to Avignon, only to be told upon arrival that Marseille's rental office had never communicated the reservation to them, and there was no compact car available for an exchange. This misinformation from the Marseille branch caused disruption to my itinerary, and driving the oversized vehicle through small towns was both challenging and fuel-inefficient.
Third: While making the payment, the Marseille rental office charged me an additional €75 for a one-way drop-off fee, promising to refund it along with the deposit upon return (we have audio evidence of this). However, at drop-off in Montpellier, the staff insisted the €75 one-way fee had to be charged. Even after showing them the rental breakdown, they agreed to process the refund but, to this day, it has not been issued.
Regarding the return process, I encountered three major issues:
First: The navigation showed the return location as being within a seven-story parking garage. After parking the car, I spent a long time searching and eventually discovered the return point was on the basement level. I had to pay parking fees to move the car to the basement floor. Then, I had to walk to the rental office inside the train station, only to have the staff accompany me back to the basement to check the vehicle. The process was overly complicated as the rental office is inside the train station with no parking in front, and there was no prior instruction explaining that the return spot was specifically in the basement level.
Second: Upon inspection during the return process, the staff pointed out a pinhole-sized crack on the windshield. Despite our thorough inspection when picking up the car and recording a video of the car, we completely missed this tiny crack. After repeated confirmations, we were certain there was no collision during our rental period. Following further investigation, the staff verified that the crack was not our fault and we were not held liable for it. However, this issue delayed our return process for an hour. Luckily, we had allowed sufficient time to catch our train, or this could have disrupted our travel plans.
Third: During the final billing, the rental company still deducted the €75 one-way drop-off fee. Despite presenting evidence and arguing our case, they merely stated that the refund would be processed later. To date, we have not received it. We kindly request Zuzuche's customer service team to assist in recovering the overcharged one-way drop-off fee.

The rental company seems to be trying to overcharge. I purchased all the insurance through Zuzuche but didn’t buy the company’s own insurance. When I returned the car, they purposely caused trouble and made me pay nearly 200 euros more. Additionally, during the negotiation process, they claimed I returned the car late, saying that the time spent negotiating meant I had not yet returned it. This was completely unreasonable, and they charged me for an extra half-day rental.

Possibly due to the language barrier, she thought we couldn’t understand her. She rushed through the information and was very impatient, and in the end, we were inexplicably charged extra.

There was hardly any queue when picking up the car. The customer service was great, and both pickup and drop-off were very convenient.
