Overcharged but didn't explain it. Charged my credit card without permission.

1. The breakdown and origins of each fee were unclear. I never received the contract after picking up the car. They said they'd email it in 3-4 hours, but I never got it. The detailed invoice was only provided when returning the car, and it wasn't clear enough; 2. We booked a Volkswagen, but they gave us a CUPRA at the same price, despite having reserved the Volkswagen well in advance and arriving on time. The car rental company switched our car under various pretexts, which was unreasonable and resulted in extra costs; 4. On the return day, the car was fully refueled and had no issues, yet the invoice included a full tank refueling charge... 5. We only agreed to the full insurance, an additional driver fee, and the cross-border fee for driving out of Germany. No other charges should have been applied. Besides the 5200 RMB for the rental, my credit card was overcharged by an additional 8000 RMB, with excessive extra fees.

Scam company! They charged me an extra day's rent for arriving an hour early. They silently added insurance without informing me. In the end, they charged an extra 200 Euros, which is over 2000 RMB!

Very satisfied

It's crucial to buy full insurance due to fraudulent behavior concerning car damage. No damage was noted at pickup, no collisions occurred during the trip, but they claimed the rear was rear-ended and there were many scratches at return, asking for €1698 in compensation. The loss would have been significant without full insurance.
