It's crazy enough this will be fixed soon.
Years ago I found an actual hidden error in my bill. (This was early 2010s). The system was calculating the EC2 reservation savings incorrectly for some of my servers. I was crunching all their detailed usage data on a regular basis in an 18 tab spreadsheet and couldn't get it to fully reconcile. I spent months trying to track down the discrepancy. Once I found it, I had to convince AWS their system was wrong, which took another big chunk of time. Meanwhile the discrepancy continued to accumulate.
After 14 months I got a $7,000 refund. I was told it had to be approved by the head of AWS. I've never seen a calculation error on their part since.
A couple of my coworkers think I’m nuts for watching cost explorer so closely but
1. The time it takes to look and notice costs that don’t make sense easily pays for itself, and then some (in my experience). I doubt you spent $7k of your time tracking this down, and you probably noticed optimization opportunities that saved you even more
2. I hate the idea of wasting money on buying Jeff Bezos a bigger yacht

Its going on for 12 hours. Looks like the humans can´t understand the agentic code that was checked in....

$7,000 of credits is no problem. At that time a friendly neighborhood PM or director could issue the credit without much oversight.
Your problem is the time period. Amending a bill in the same cycle is EZ. Fixing the previous cycle is a PITA but pretty common. Issuing amendments for the previous financial _years_ would be a huuuuge PITA going through finance etc.
