LG Electronics - Refrigerator Not working for last 2 months

I bought refrigerator of LG * years back by spending my hard earned money of almost ***** rps.
After so many complaints to company for almost * months finally technician told the fridge cannot be corrected anymore and we got approval for fridge replacement on *th september after ** days of struggle.
Now the person who is handling the complaint told that we will get **-**% depreciated value and we need to pay extra **-**% value look
What is fault on consumer side,We are suffering for almost * months and now why we need to pay extra amount.Strange but we are mentally torched by every team member whom we recieved communication
