I will elaborate: I started out with AWS several years ago. I could never work out how they calculated my bill, and had more than one >$100 shocks for hosting my personal services.
I moved to DO and Vultr (stayed with DO for no real reason) and so shut everything down on AWS.
But I still got a $0.50 monthly charge on my credit card. I tried emailing - no response, totally ghosted.
I went through the control panel several times - it is/was a huge mess, obscure by policy obviously - and finally in some far distant corner found something still turned on. I did not understand what it was at the time and can recall no details, but I turned it off with great relief.
A week later I got a email from AWS (!) saying that I had made a error and they had helpfully turned the whatever it was back on...
So I continued to donate $0.50 a month to Amazon until I cancelled the credit card for other reasons. (it would cost $10 for the bank to even think about blocking them)
These days I will crawl over cut glass not to do business with that organised bunch of thieves called Amazon.
