According to the terms and conditions, people that cancel without using any Prime benefits (such as free shipping or Prime Video) could also be automatically eligible for a refund.

However, consistent with DoNotPay, you'll request a partial refund for the remaining time. It seems to be hit or miss on whether or not you will get one, but it's worth contacting Amazon support and asking.

I contacted Amazon's chat support while researching this text and was quickly told that there have been no refunds given, but you'll have better luck than I did, especially if you're fully closing out your account. DoNotPay recommends calling Amazon support or using the Contact Us form rather than chat.
