The trick is balancing account privacy with fraud prevention. Without being the account owner or having any real relationship with Amazon OP has a hard task of proving who they are and generally you wouldn't want Amazon sharing any account information with non account owners. I think the real solution would be for them to just provide an auth mechanism for people to prove they are the CC owner so they can remove the payment method from any accounts and not give out any info on the name or email on the account. I've seen a few things that use a small charge that gets refunded and you enter it back in the app as a 2FA.
