LG Electronics — Replacement of L.G. Double door refrigator

I had purchased l.G. Double door refrigator from snehanjali on 14/10/14. On 24/10/14 I had made my first complain with the store as fridge was not working properly. At the time of purchase I was informed that if any problem persists within first 15 days I will get new piece as replacement from company. Problem is that in the lower portion of fridge where we can keep fruits, vegetables and any other things gets extra cooling and all our items gets freezed. Till today I had made complains around 10 times and many different persons from L.G. Had came but nobody had solved our problem. So kindly look into the matter and replace our fridge as early as possible.
