LACK OF CUSTOMER SKILLS

I went for my lessons with TKC driving school and my instructor was fiddling with his phone while teaching me and when I make a mistake he raised his voice at me as if I know what I am doing. I went to driving school so I can know how to drive. I would not go there if I know how to drive. And it was my third lessons and we were driving inside town and with lots of cars were you can easily cause a serious accident.
