It looks you are a new driver who does not have any experience in driving. You were not able to control the speed of your car while turning to a side road means you are putting yourself and others in trouble. You were lucky not to hit some pedestrians there which could have taken you behind the bars. You should have bought a second hand car and learned to drive properly in the late evening when the traffic is very low rather than buying a new car and crash it within 4 days and spoiled the gear box.
