I'm contacting you because a problem I'm having in my driving school. I had already finished all practical classes but due to problems on the simulator, two of them wasn't accounted by DETRAN system. The director of the driving school asked me if I would like to change these classes for other practical classes in the car, since this problem could happen again if I made new lessons on the simulator. I agreed, but believe it or not, I still had to pay $ 50.00 per this change. By I receipt my permission to drive, I'm thinking to process both the driving school both the DETRAN. I find it very hard to do, since it involves a lot of bureaucracy and to tell you the truth, I never processes anyone. You, as a good lawyer who is, what would be your recommendation to solving that case?

Agradeço quem puder ajudar!!!
