I would never discount one person's report, especially one as thoughtfully presented as yours. You are obviously an experienced visitor who was legitimately disappointed in your experiences this trip.
But I also hope people don't think that this means there is necessarily a pervasive issue with customer service and interactions. We have visited four times since reopening, including just a few weeks ago, and had some of the most magical, friendly, helpful, heartwarming interactions with cast members that we have ever had.
I do hope that if/when you return, you have a better experience.
Yes I totally agree with everything here. The OP's description of their trip was heartbreaking. It's so disappointing when a trip goes so much differently than planned. And some of the things described here are unacceptable and need to be corrected. But I agree that it seems, very sadly for the OP, like a series of extremely unlucky events coming together here. We have had totally different experiences lately a WDW. BUT that being said, I will never forget our Disney Cruise flight delayed-baggage mishandled-almond milk explosion-spent the whole night doing laundry-ground transfer never showed up-two hour wait at the port-why is our bibbidi bobbidi boutique appointment missing-kid ran into a pole and broke his glasses on embarkation night-Guest Services screwed up our rewards card-fiasco. It was rough, it was one for the books, and we can laugh about it now. But it's awful when it's happening.
