You didn't explain why you didn't want to share your ID with Amazon, but it's not an unreasonable request from them as a way to combat fraud.
Amazon got so large they stopped paying attention to the details.
I wonder how much a 20-yr old Amazon account is worth on the grey market. Mine is about that old, and I have – legimately – returned thousands of dollars worth of goods (that were faulty or just didn't work the way I liked) and it is probably very difficult for Amazon to distinguish between my legitimate returns and a hypothetical alternative where I'm a fraudster that just purchased this old account and am laundering broken electronics through the returns system.
It's not only Amazon that has this problem btw. Lots of online stores do. Return fraud is so prevalent that you should expect to this to become more common. A few bad apples ruin it for the rest of us.
Payment details aren't enough to reliably establish identity in many cases. If fighting this stuff were easy they'd have done it already, they aren't idiots.
And crucially - Amazon doesnt do this tracking on purpose so they can have plausible deniability while screwing merchants.
Btw, if Amazon is a fault, where they can't shift the loss onto a seller or third-party, the delays will go on for weeks, if not forever. You have to do a chargeback.
"Aged" accounts are a thing you can buy on the black market, as well as hacked accounts of users with long chains of legitimate activity. It's not as strong of an anti-fraud signal as you might think.
They can use common sense for the refund. They are just choosing not to.

They should inspect their returns more carefully before refunding.
Amazon can't verify everything, but for it's own Fire devices it does check S/Ns. Also Apple has it's own system, they do not mess around. I suggest not buying Apple products from Amazon.
When I contacted customer service, they told me I had to send them a copy of my ID to process the refund. I was really frustrated; I’ve had this account for over 20 years and never had any issues before. I spoke with several representatives, but they all gave me the same response, and a few were even rude and aggressive, something I’d never experienced with Amazon before.
Since I didn’t want to share my ID, I decided to go through my credit card provider (Visa) instead and filed a claim. Visa refunded my money, but shortly after, I got an email from Amazon asking why I’d raised a Section 75 claim (the UK’s credit card protection scheme) and informing me that my account would be closed for fraudulent activity.
I replied with proof that they had received my return and never issued a refund. That was the last I ever heard from them, and the last time I bought anything from Amazon.
