I purchased full insurance from Zuzuche while renting the car, but the rental company didn't accept the policy. After a long discussion, they agreed to accept a €1400 deposit and a €100 full-tank return deposit. When returning the car, the staff clearly indicated that the vehicle was in good condition and the tank was full, and that the deposit would be returned on the second working day. It's been almost a month since the return, but the €1400 deposit has not been refunded, and €77.29 of the €100 full-tank deposit has not been refunded either. Despite Zuzuche assisting in the investigation, there has been no feedback. I've used Zuzuche many times and have never been so disappointed. I hope for a prompt response.
