Is the Amazon call about a suspicious charge a scam?
This is a scam
A typical version of this message
This is an alert from Amazon customer security. A charge of $749.99 for an iPhone has been placed on your account and is scheduled to ship to another state. If you did not authorize this purchase, press 1 now to speak with an account specialist and cancel the transaction.
Why it is a imposter scam
Yes. Amazon does not call about suspicious orders and does not use 'press 1' menus for fraud. The invented iPhone charge is bait: the 'specialist' will ask you to install a screen-sharing app, log into your bank to 'process the refund', and then manipulate the screen or talk you into transfers. The scam is not the fake charge — it is the helpful person who removes it.
What to do
Hang up. Open the Amazon app or type amazon.com yourself and look at Your Orders — the charge will not exist. Never install software or open your banking app while on the phone with someone who called you. If they had you log in anywhere, change that password now from a device they never touched.
