When booking through Zuzuche, I noticed there was a mileage limit on the rental options. Therefore, I didn't purchase Zuzuche's insurance but planned to buy the car rental company's insurance on-site and have them remove the mileage limit clause. At the car pick-up, I asked if I could buy full coverage without any mileage limit. The staff assured me there was no mileage limitation. Since the contract was in Portuguese, I trusted them and didn't translate it word by word. However, when returning the car, they still charged us for exceeding the mileage limit. I felt deceived, but since I signed the contract, even if I filed an after-sales complaint with Zuzuche, based on my years of experience with them, they would definitely not sincerely help resolve such issues. So, I could only accept my bad luck and consider it a costly lesson!
