Bosch Home India — refrigerator noise

Address:

Dadra and Nagar Haveli, Dadra and Nagar Haveli, 396230

My bosch refrigerator 347ltr is very noisy, this noise is more than normal and it disturb very much. I complaint after it delivery but it's of no use.
Now the noise increase and it's unbearable.
The compressor noise is clearly sounds bed and one more sound is there like whistle.
I m very much disappointed by having this type of noise in the company like bosch and the response give by the service center person. I have clearly mentioned about the noise on feedback form and i m not satisfied with the response given at the time of visit of your othorised authorised service centre engineer.
I hope this time the company will look in to the matter and resolve my problem, it will stop me to take more aggressive steps.
