I have purchased a LED TV on 13 NOV 2011.TV suddenly stop working on 1 Feb 2016, I have given the complaint to Samsung and engineer visited to my place and told me the mother board is malfunctioned and need to change and ask for the advance, I have given 3000/- as a advance.
after few days I got a call from Samsung saying part wont be available and they can give me some amount back as they are not able to support. I was told that TV is 5 years old to there will be 83% depreciation and I will get only 17% of the TV cost. I denied for that amount as I paid 75K and my TV doesn't last for 5 years. I was told that TV life is at least 10 yrs (i.e. 20000 hrs) when i was buying the TV however the lady who called me from Samsung(she was very rude) told me TV life is only 6 yrs. so my question if Samsung as a brand they are saying TV life is 6 yrs why should we waste or our money to branded TV. and how they are calculating 83% deduction, and i think it should be 60% and I should get 40%. If branded TV doesn't last for 10 yrs then no one will go for branded TV.
