Caller: Amazon scam

Usual stuff, claiming that unless I cancelled my "Amazon subscription" they were going to charge my "account". Which I don't have. I tried the usual thing of getting them to try to explain what account, but they're now saying that it's company policy that they don't provide details of the account over the phone, I have to provide information to them (sure...). After singing "if you're a scammer and you know it clap your hands" at them, I hung up.
