Samsung India — refrigerator not cooling

Address:

Kottayam, Kerala, 686541

I first complained on 12/9/18. I received a job no:[protected] and the technicians phone number. When i called him he said he has not been assigned the job. And that was it.. No information since then
I kept on calling customer care thrice everyday with my job no. Still no response. I have lost a lot of food and medicine. Whom should i call??? Yesterday customer called me and said that a technician will come today, sunday!!! So then i asked are you sure since it is a sunday... She definitely yes. No one turned up. I am a working person... I cant for a someone not coming. Why are you so irresponsible.??? Wil never refer a samsung product!!!
