Amul / Gcmmf — Bad or very poor quality of icecream bricks

I already complained to Amul customer care via email but Amul service is very disappointing. This is reg bad or very poor quality of icecream bricks which I purchased from my near shop. It’s smelly and like rotten medicine taste.
Amul should feel shame why they unable to resolve customer issue despite being asked many times. If this is continue Amul will soon be closed and there are good companies coming in market.
