Samsung India — Company is not able to repair my refrigerator

Address:

Dehradun, Uttarakhand, 492007

It has been about 3 months to the complaint made by me to samsung for my refrigerator,
Their service man came and changed the sensor, but the problem remain the same,
Their different engineers visited us about 20 times, tried changing different parts but still were not able to rectify the problem.
Now, as i called head office they also sent another service men... But no solution came out.
Company is not giving any satisfactory answer and i am suffering of buying a branded refrigerator of samsung.

Please help me to sort out the problem as soon as possible.

Thanx
