Samsung — I bought a samsung refrigerator this year in may and it started making loud noises in june

I bought a samsung refrigerator this year in may and it started making loud noises in june. I lodges many complaints and the company sent two service men twice... Both times they said it is beyond repair. It is also causing sweating. And the parts of the refrigerator were also missing (The filler tray) since the beginning. I have been wanting a replacement since it's under warranty and no body has followed up. The service guys don't take my calls and nobody reverted back. This kind of service is not expected from samsung at all. The brand is trustworthy and that's what i thought and bought the fridge online but it's pathetic now! Please look into the matter is possible or the next step will be to go to the consumer court.
