There was an issue with the fuel gauge. The pump stopped when refueling was supposed to be full, but I added 5 more euros of fuel. When returning the car, it still showed a bit less. The staff said they would verify it with a colleague, but then got busy with other things. We didn't have time to wait as we needed to catch our flight, so we took a photo and left. A week later, they still hadn't verified it. They could at least refund the undisputed part of the fuel charge! Verify the disputed part! But no, they just drag it out! 108 euros, not a cent refunded! Luckily, I took a photo of the fuel gauge when I left, as evidence. Otherwise, with no proof from the staff, where would I go for customer service? Now their response is just to wait! Who knows how long that will be!
