Maruti Driving School — Worst Attitude and Irresponsible Behaviour

The person teaching in Vishrantwadi Pune driving school is having a worst Attitude. He gets irritated on every mistakes like if I am already aware of four wheeler driving and don't even bother to tell the correct approach. If classes not there they don't even inform prior and when we reach they say no classes. I have to continue since I have paid the full amount. Please change person on priority or else refund the amount.
