[Resolved]  Whirlpool 310 L Refrigerator — Sweating (water droplet collection) on chiller tray & vegetable container

We bought Whirlpool 310 Litre refrigerator 15 months ago. The item arrived with physical damage which was replaced after 15 days. Always the we found water dripping from chiller tray. Every 10 days some engineer visited and never solved the problem. They changed door first and replaced refrigerator completly just at the fag end of warranty. Even on the newly replaced refrigerator, we found water drops on vegetable tray. We had been complaining continuously and the service franchise keeps the call on observation always. Now whirlpool want us to pay 15% towards depreciation as a precondition for replacing this defective piece. We are not sure if product design itself was faulty. All vegetables are getting damaged everyday and our suffering continues.........Can any one give us solution
