I bought a Samsung refrigerator on May 25th and its not working any longer. Called customer care everyday and they said someone will reach me, but nobody has given me any information. the tech visits happened initially 3 times he came and said he needs to replace some or the other parts. However, nothing has been replaced yet. nobody tells me anything and I feel helpless and cheated. how can I get such a bad new refrigerator, its just 2 months old. I think I deserve a replacement. please help me.
My case no. with Samsung is [protected].
