The Alamo at Milan Airport is subcontracted to the local rental company Locauto. The vehicle was in great condition, and there was no pressure to buy additional insurance. However! At the counter, they initially asked if I wanted to add prepaid fuel. After asking about the price and policy and finding out there's no refund for unused fuel, I declined the prepaid fuel option and confirmed with the staff that I would return the car with a full tank. I didn’t add any extra services. But! The staff secretly added a €115 fuel charge to the contract. At the time of return, they assured me that the €500 deposit would be fully refunded and didn’t mention any additional charges! After the deduction appeared on my account, I contacted the branch. The staff admitted it was a mistake made at Milan Airport. They provided us with the rental contract and proof of the full-tank return and also marked it in the system, instructing us to request a refund via customer service. Then, I emailed customer service politely with all the evidence, but they refused to acknowledge it! They insisted that we purchased the prepaid fuel service. The situation is very clear—if they could admit their mistake and issue the refund, we could move on. But with this kind of attitude from customer service, it's obvious they're trying to scam us, so we’re prepared to fight this to the end.
