Samsung — Side by side Refrigerator

I have purchased this refrigerator in 2014.. there was some cooling issue with the freezer so o called up customer care..
the executive came and said has needs to be filled.. so next day another executive came, he said there is some internal leakage and some nitrogen test needs to be done.. but chances are we can’t do anything for internal leakage..
I bought such an expensive defected product from Samsung…
Who changes fridge every 8-9 years??
Is this really Samsung ??
He offered me 10% on the bill amount… like really??? Am I begging you???
There is a 10 years warranty sticker on the refrigerator… so incase on internal leakage or defect is it not your responsibility … from. Where is it my fault??
