Many compounding issues with iTunes Match and iCloud Music Library

So many issues I don't even know where to start. Multiple iOS Reps are not being responsive. Been struggling with iTunes Match since last year.

Ever since upgrading to 12.2.1.16, my iTunes Library self-destructed. First it added album ratings to dozens of albums (including Unknown Albums) that forced thousands of songs into my smart playlists. It wouldn't let me change or adjust the album ratings - all greyed out and bounce back if I try.

Then it stopped syncing between devices. In My Top Rated (5 stars) I'd have anywhere from 592, to 1736, to 2066 songs.

A few days ago it stopped streaming entirely - my entire library just disappeared for an entire day. Eventually reappeared.

This morning all of my song ratings disappeared, when the ghost album ratings are still there. My iPhone lost all of its playlists, despite being signed into iCloud. It also is only displaying around 100 random songs sampled from my library of nearly 10,000. None of them are supposedly Ma[d]e Offline, none of them have Remove Download. But they all play immediately without buffering - so they must be on my phone.

I'm sitting here writing this not even touching iTunes and the numbers of songs in my iTunes keeps fluctuating.

So incredibly frustrating. I basically throw money at Apple -
