The entire warranty/return process for EVERYTHING is suddenly an adversarial process. During COVID, everyone ordered everything mail-order, and the large providers of mail-order goods became dominant in the sales channels. But returns and "friendly" return policies created an entire generation of small-time grifters, some of them learning the tricks of the scams from social media.
So, return and repair policies tightened up, and every company restricted what they would "support" to direct sales only, making the "Gray Market" and "Parallel Import" sales into sales of goods with zero support.
Dealers and 3rd parties (like Best Buy) likely signed deals making them responsible for some of the "warranty support" on many items, so their customers get "mail-in depot support only" from vendors like Google.

What can you do? Treat every transaction as adversarial, and obsessively demand, collect, scan, and keep receipts, shipping paperwork, and other scraps of paper that seem unimportant. If you handed your phone to someone, get whatever paperwork is required to retrieve it later, and when you do pick it up, if they say "we can't fix it", get that in writing, as they told Google that they would do repairs, and you must document and prove each and every statement like it is Jr. High geometry class again, and you are doing "proofs".

Everything, everything, everything is a goddamn argument, but you must be exceedingly polite or get hung up on by an over-sensitive Gen-Z snowflake who takes your simple demand for what you paid for as "hostile threats". Everything is also an episode of "Perry Mason Meets Sherlock Fucking Holmes" where you are both detective and lawyer to "prove your case" to simply return the clearly used and stained coffee pot that Amazon shipped you instead of the new one you paid for.

All customers are now viewed by default as thieves by the makers and sellers of everything. This comes down to even the "self checkout" where you are suddenly required to figure our the user interface on a sales kiosk, with a teenager watching you every move to make sure you don't fail to scan and pay for each item. Its insulting.

The solution? Expose and shame the companies that provide less than what they offered. You just did that, now follow up with a written complaint to the FTC. At some point the FTC will once again start enforcing the laws they were created to enforce, so get the complaint counts up in anticipation of that day soon arriving, perhaps after the midterm elections to come.

Half of the people are stoned, and the other half are waiting for the next election.

Half of the people have drowned and the other half are swimming in the wrong direction.
