Counter agent at Treviso airport was fantastic, absolutely wonderful--- helped me call a credit card company and was incredibly kind and relaxed. The first car had an engine problem as soon as I started out from the airport, and had burning smell. I returned in five minutes, and the mechanic/drop off agent inside the garage yelled and me and called me an idiot, said I did not know how to drive a car and I was ruining his day. Two other rental company agents were there, and clearly saw the car problem, told him to calm down. I went back inside to speak with the rental agent and change cars--- he was wonderful and explained that the company has problems regularly with the gentleman outside. I was able to drive away with a much better, safer, well-running car, but only after the same garage employee said some horrible things to me and threw the new car keys at my face. What happened? I have purposefully chosen Sicily By Car for this important rental, as I have always had good experiences. I will, sadly not rent again. unbelievable, at Treviso.
