I don't know why there are 30 windows, if only 4 or 5 work! I have been waiting for 3h to be attended and the slowness, will still take more than 1h. Nonsense! To get here, it's a harassment of people who get in front of our car, offering signs and I don't know what. Another nonsense! In the surroundings is difficult to park. It is not possible to have this type of service when there is a structure to decrease the waiting time.
