My bank just said that there was "no error" when I did this after Amazon failed to deliver something last year. I imagine that Amazon makes up a good portion of their chargeback complaints now.
Separately, I had my bank block Amazon Prime from charging my debit card. It shows up as a different merchant so they were do it and I can still make one-off purchases (which I don't like to any longer). I did this because the UI to cancel Amazon Prime did not work on my new, updated MacBook. It did not respond to clicks on the "confirm cancel" or whatever button.
