The customer service was not familiar with the procedures. They insisted that a translated driver's license was not acceptable and required an international driver's permit. Even when their colleague informed them that the translation was valid, they continued to insist it was not. Finally, their colleague had to explain the situation to the supervisor. After talking to the supervisor, they still emphasized to me that I must use an international driver's permit next time. Not sure if this is an issue with communication between the rental platform and Alamo or if the Alamo staff is just too incompetent. I am not satisfied with this rental experience!
