Honda Cars India Ltd. — back seats jump a lot while driving

Address:

Coimbatore, Tamil Nadu, 642126

We had bought a honda city from your coimbatore show room, last october. Ever since we started using, the back seats (Which are positioned directly over the rear tyres) are really not comfortable, as they tend to jump whenever there is the slightest irregularity in the road and for every speed breaker. The local service center told us it will improve with time and also to reduce the air pressure if the tyres. Neither of it helped. Kindly resolve the issue as it is really becomes uncomfortable, especially while traveling in roads within the city.
