How can I recover deleted Voice Memos on my iPhone?

So, here's what happened:

I deleted the voice memos app. Reinstalled. Only got the files that were pending "download" and stayed like that, now they're on my voice memos and can be actually listened to since they're no longer "downloading".

BUT, my most important recordings and one that is 6 hours long is just gone. It's disheartening to see my data being lost at this point. My phone is not backed up but on the iCloud settings it says voice memos IT IS supposed to be backed up.

Side note: I also used my Apple Watch and recorded 7 hours of a presentation that is extremely vital, it showed on my Apple Watch, but then it never transferred to my iPhone. Where's that recording? Is it lost? The Voice Memo App kept disappearing and appearing on the watch but the recording isn't there. I only got to play it one time and then poof it went up in smokes. I had Bluetooth and Airdrop on and I was hoping the file would show on my iPhone.

I had WatchOS9 then updated to the most recent version, and restarted the watch.

Please tell me there's something that can be done.

I shouldn't get angry with people offering their help, but it gets annoying when all I hear is parroting of the same links, that are of absolutely no help, since I mentioned already the iPhone was NOT backed up. The voice memos are nowhere to be found both on the Watch and on the phone.

The deleted folder is nowhere to be found, it only comes up when I tried deleting a test memo.

I am so desperate I am even willing to pay for the recovery of this 6 hour recording.

Apple support is of no help.

Same frustration monotonous answers.

I hate Apple.

Never buying an iOS device from here on.
