Hyundai Motor India — overspeeding of engine even though neutral gear position

Address:

Gandhinagar, Gujarat, 382016

My car was serviced by punjab hundai gandhinagar on 4/6/17. Also furthur inspected on 29/6/17 for panel base work in car. From that service date, my car's engine rpm does not get of[censored]nder neutral position. Car's engine runs at overspeed eventhough not accelerated by me. Also unwanted noise comes from engine eventhough insurance job work done at same place. Thus i request you to solve my complaint.
