During the trip, the car needed more AdBlue, so I bought and refilled it myself. When returning the car, I explained the situation to the counter and requested reimbursement. The staff asked me to email customer service with the details. Using the email provided by the counter staff, I contacted customer service and provided the receipt. Within a week, I received a refund of 28 euros.

Pushed for insurance

They tried to upsell insurance, just decline it.

Very poor experience. Rented a car for someone else, but upon arrival, they were informed that the chosen model was unavailable and suggested an alternative. Despite knowing the renter had poor English, they intentionally did not clarify the costs. Various additional charges were applied for upgrades and lower insurance coverage, making the total upgrade costs higher than the rental fee. All these were not clearly explained to the renter! It took almost a month to resolve this with such a terrible rental company. Be cautious! Similar issues with unjustified charges occurred with an order in Germany despite having insurance purchased in advance from home, only to be charged for reduced coverage at the store. Terrible.

The car model was changed. I booked a Mercedes station wagon but got an Audi A4. The trunk couldn't fit two pieces of luggage. Downgraded the car and effectively increased the price.
