Bosch Car Service — poor service & parts charged more than showroom

Address:	560077
Website:	boschcarservice

I have changed my fiat linea car suspension at bosch car service. I feel they are charging more than oem parts. I got delivery after a week with delaying in getting parts. After a week i noticed car wobbling while applying break so i dropped my car for alignment and break check. It got rectified ad took delivery in the night. Next day morning when i see the car front bumber got crack and grills are broke. Being my car black in the night these were not visible, so they silently delivered my car. They have hit my car and broke my front bumper and grills. Please address my issue and do the justification.
