Looking for reliable 3rd party MacBook repair in Bangalore

My MacBook Air M1 stopped working after 1.5 yrs, I got it checked at an authorised service centre in HSR and they’ve come back with a quote for 44k. This version of MacBook with the same specifications is now available on Amazon in the ~55k range, don’t want to spend this amount on the repairs.

Anyone who has some experience in getting apple products serviced from non-authorised centres?
