Don't feel too bad.
I've been at places where the AWS annual spend was a real lot of money, let's say way over 100k but not 1 million USD.
Support tickets went unanswered for months, assigned account reps left us hanging for months with multiple follow ups, etc.. All tickets opened within the last 6 months got AI generated responses with massive delays that indicate the ticket wasn't read by a human due to how inaccurate the response was based on the questions asked.
This where I don’t get the HN flame at Google.
I had an obscure KMS issue a few months ago, I reproduced it and opened a ticket. It was a low severity. A guy emailed me back in about 4 hours, acknowledged it and thought I was doing it right. Came back 2-3 days later noting that it was a bug, and would be fixed in a few weeks. As a workaround he updated my script with a less obvious/efficient solution to get me through.
