Amazon member since?

I was just curious. Seems like it would be easy to find. Finally asked to chat with someone. They told me I’ve been a member since 2014. I told them that was incorrect. I said you’re at least 15 years off. They proceeded to ask me for the order-id. Which I gave them. They then asked for the tracking # which I don’t know. Why would you need the tracking #? At that point I ended the “chat” because it seems I knew more than they did. I’m pretty sure Amazon use to say “Member since…”. Anywho… don’t know why I felt the need to hide the order # after 26 years. Guess I’m just paranoid. Also I know I screenshotted the chat, because that’s what I do, but evidently it went to /dev/null/ because it’s nowhere to be found.
