The first day the vehicle had issues, but they were quite sincere in resolving the problem. They sent a taxi to pick us up, but there was no vehicle of the same class available. The second day in Annecy, we were told again that no equivalent vehicle was available. On the third day in Lyon, we felt the car was too small, and they refused to give us a higher-class vehicle, even though we were not originally planning to go to Lyon! This greatly delayed our trip and wasted our time and money by having to detour to Lyon just to change the car! For these two days using a lower-class vehicle, I request compensation. You can't just refuse to compensate because you don't have a vehicle available. When I requested an upgrade, they refused.
