Amazon and Google for that matter never take time out to call or contact people regarding their services. Anyone who does call claiming to be from these companies is not a real employee. The same holds true with the IRS and other government agencies.
Yahoo account holders may recently noticed Order Confirmations from Amazon that are not actually their purchase. Since this seems to happen through people who have real Yahoo registered email accounts through Amazon, it may be the case that some Amazon shop partner within the Amazon network – like a reseller or someone else in their network who got infected or lost a laptop or something. Either way, your information may have been breached – as far as email address is concerned. If the breach could have included credit card information, there would be no need to ‘confirm’ the cancellation of a purchase.
Here is how you view the Yahoo email header for a particular email:
Amazon has offered up a link on their site to report these fake emails. Log into their site as your user. Click on this link Amazon Spoof Reporting form.
If you spending a little time copying and pasting the email header (one click to see the header on the Yahoo email) it will help them identify the problem and get this resolved by Amazon.
If you have Yahoo mail and you received these fake spoof emails, emails showing orders that are not yours, you may want to pull up the email in Yahoo again, and then choose the cog icon along the top of the email, and select to view the header. Copy the entire header and paste it into the appropriate box on the link from the Amazon Spoof Reporting form.
