Your issue wasn't because of a faulty battery though, it was normal battery degradation. You would have had to pay for a new battery in any case. If it was less than a month ago you might want to try to press them to refund the difference, but otherwise you did get a tangible benefit from the new battery in the time since you replaced it, so there's a cost for that.

Normally degraded batteries are still usable at 50% charge. If the remaining capacity was truly unavailable they should not have been displaying a fictitious state of charge. But of course, then the pitchforks would be out right away with no chance of hiding this slick way to force upgrade sales.
The real reason why they implemented this extreme method of "protecting" the battery is that they are deathly afraid of what will happen when these older batteries are fully discharged.

This happened regularly on all my laptops, though, so it doesn't surprise me it was happening to people's phones. Reported percentage was based on design capacity instead of last-full capacity, and shifted so 100% is "Full". So when the percentage reaches right about the point where all that's left is the degraded part of the battery, it suddenly jumps to about 3%.
(Since figuring that out almost a decade ago, I've been using my own battery-monitor script to see both percentage and health, so it's easy to see what's going on and just how bad my battery has gotten. Maybe the default notifications are better now?)
