When driving on a rough road (not bumpy) but with lots of stones or rough terrain, the inside of my car buzzes. The sound seems to be coming from the door near the driving seat.
Attempt # 1:
I had it checked from Margalla Motors, they said there's some vibrations and tightened the bolts and screws of the door panel. Not fixed.
Attempt # 2:
I then had it checked from an interior guy (National Autos near Tariq Road) and he tightened the screws again and this time from the speaker's side. Changed the door panel clips and also attached some foam. Not fixed.
What should I do? When I drive on rough hilly roads, it vibrates more.
Video of the noise (I placed my phone near the noise, it's not as loud as the video sounds but you get the idea on the vibration)

I have also noticed that sometimes If I hit a bumpy road, a metal rattles and seems like its from under the car. I got my car this year and it should not rattle/buzz.
(The car was also affected due to flood, had to interior clean it and also had an accidental damage from the behind).
