This is not my experience. I had a package simply not arrive, and Amazon AI said it would replace the missing package (which was a high dollar value). Instead, it just repeated the order, double charging me. I had 3 conversations with human CS promising me they saw the mistake and would fix it, and never did, so I was double charged. After months trying to resolve it I eventually gave up and ate the cost.
I've never had such a poor experience, including being repeatedly lied to by CS, and this was the last straw for me. I honestly don't miss Amazon, I buy less stuff and feel better about it.
If you have evidence of these conversations and so on then you can do a charge back on your credit card.
