I submitted my Macbook to Apple authorised service centre and as part of their official protocol check , they damaged my motherboard and now my MacBook is dead

Excuse me? Most of the time when I bring it in for service, they offer me a 90 day warranty on their repairs.

I would call Apple Customer Relations. Same number as AppleCare. When you get a real person, ask to be forwarded to them and give them your case number.

Complain the authorized service provider is asking you to bear the brunt of the repairs, and you think they need a better insurance coverage, and that Apple needs to help out. That's what business insurance is for. If the provider has no insurance, it is negligence on their part for not having it. We can't question Apple's policy on this board, and I'm only telling you this from my perspective as a user.

This is primarily a user-to-user technical support site, and none of its participants have the ability to escalate your concern.

Hi

I’m having same issue apple service centre reported me that my mac pro latest model motherboard is dead and they have no reason to explain. They are asking ₹55000 to replace new motherboard which is too expensive and I can buy another brand less than this cost. But what to do with this dummy now plz can you tell. Its just been an year and this happened after expiring of warranty date.

Take it back, they owe you a working machine. But you're going to have to supply proof Apple damaged it. No idea what that would look like.
