Apple India — laptop damaged by apple service center

Address: Rednam Gardens, District court road, near sbi, 530002

Laptop was given to the apple service center as it was auto shutting down sometimes but they called after 2 days and said it is not even turning on and refused to take any responsibility for same. We called the apple customer care service centre multiple times they are telling let service centre decide and service centre said let apple decide. No one is ready to help. They are not ready to accept their mistake.
