Avis Car Rental Orlando, FL Airport Avis Scammers Rental Orlando Florida!!. Be aware of what do you sign, they offer me a free upgrade since they didn’t have the economy car I prepaid and two weeks later they charge me $105.44. The charge was disputed with my bank, now Avis is sending me letters charging the money. I called Customer Service and their answer was that I sign the agreement and if I enjoy the car I have to pay. I trusted the good for nothing employeer and he lie to me right to my face. They lie and make you responsible of their lies. If you had the same experience please share with others. Do not rent cars from Avis, please read their reviews.
