Apple India — macbook air 2015 model:automatically logic board being damaged

I went to ivenus service center as my macbook suddenly stopped working. They told that logic board has been damaged on being asked the reason behind it, they said due to temperature and being in sleep the logic board got damaged. And now the product is of no worth as the logic board replacement cost is rs 43, 500. Is apple products not sustainable to temperature change. I did not find an apple product worth 65000 rs to be zero in two years without the customer being at fault. Please think now before buying an apple product.
