There are 2 reason what Amazon payments were not successful:
The payment was declined by Amazon, so we weren't able to process the payment. In this case contact the Amazon team for resolving this issue.
You were attempting to use Amazon gift cards as a funding source. This type of source is not supported outside Amazon.
Our security system declined your payment attempt. If funds were withdrawn, the transaction will be instantly refunded to your Amazon account. Reach out to our support team so we will be able to verify your payment account.
