Counter staff tried to upsell to more expensive car, tried to sell insurance package although I had full insurance already

There was a minor issue when we rented the car. We asked the staff for an electronic toll collection device and they said they had one. We signed the contract and the staff, probably eager to get off work, didn't include it properly. When returning the car, we were almost fined for electronic toll fees. Thankfully, my child, who speaks fluent Portuguese, argued our case and pointed out the contract wasn't signed correctly. The return staff then realized it was a mistake from when we rented the car and apologized. It was resolved smoothly in the end.

Car rental was provided by Europcar. Although there were many people, the vehicle they provided was excellent.

The car was brand new but the engine was noisy and seemed to have trouble shifting gears even though it was an automatic and I was always driving exactly the speed limit. I was pressured into buying $600 in insurance for the one-week rental because they said that if there was even a small nick in the paint from a rock I would owe tens of thousands of Euros. The woman at the sales desk wrote down some huge numbers of fines that I would be charged. I returned the car with 600 km of mileage and in perfect condition -- but I had been pressured to buy a ridiculous amount of insurance. I will not rent from them again.

We didn't get the car we reserved. They over-booked and we waited over 2 hours to even get a vehicle. The vehicle was different than what we wanted. After the entire experience, the drop-off location closed 5 minutes prior than they are supposed to and sent us to a different location. By the time we reached the location, our formerly full gas tank was no longer full so they advised us to drive 15 minutes away to re-fill it and come back to return. Upon return, they over-charged us for the vehicle and I need to get this sorted out. Europcar is not responding to my emails.
