I have given complaint to samsung customer care[protected] for double door fridge 321 litre refrigerator Top Mount Freezer RT34M3983B7 repair on July 27th, 2021. Samsung representative visited to my house on July 28, 2021 and verified the refrigerator and said that censors has to replaced and took 300rs advance from me. After this contacted so many times dealer and customer care but no use, issue is not resolved till now today is Aug 29th, 2021, it's been more than a month. As they did not solve the issue for more than a month fridge get worst than previous, so I need replacement with new one.
