Capital Honda India — Dashboard Rattling Noise

Address:

Capital Honda OMR

I have bought Honda city car in 2019, it was nice when i drive in the city and when i go to high way when ever i ran over the lines speed breaker its give more noise in dashboard and i complained this in the service center and given it for fix for three times but it was not fixed, they says its fixed when ever they deliver the car but i can test it only when i go on high ways.

this was taken to the service Centre head too last time he said they will fix but its not. I am not sure to whom i should complain
