[Resolved]  Samsung India — services for refrigerator

My Samsung Frost free refrigerator was not cooling, called Samsung service on 4 April, 2018. Service reps. Informed that several parts had gone bad and need to be changed at a total cost of ₹ 3750/- the parts were changed, but the problemdid not go away. The next day they asked me to run the refrigerator empty for 3 hours and it will start functioning properly. I followed their instructions no improvement despite this. Have been calling the service centre, who promised somebody will call and rectify the same. Please look into this and get my problem solved.
