Had a 12.5 month old iPhone 12 mini die recently and used Apple's mail in repair service ($400.) Getting technician's notes out of them (needed for a credit card extended warranty claim) has been nigh impossible after spending hours trying to get that artifact. About 2 months in at this point and they've sent plenty of stuff; none of what I've asked for. It's equivalent to dealing with the USPS on a lost package claim.
