How do you find out what the OP is selling? I can't figure out how to find a storefront without a known product.

Google searching just pulls up a bunch of Zac Efron results.

All perfectly logical, but, most hacking successes happen because the hacked are either unaware of a problem with an email or not paying full attention in what they are doing and clicking on suspect links.

But.

If you are trying to change some part of your personal or company details you a) have contacted Amazon in the first place, and b) your giving this contact your full attention to enable the changes.

Going by the OP they were trying to facilitate a change to their account through contact with Amazon and not answering some random phishing email purporting to be from Amazon

Yes, you're right - Letters must be via Buy Shipping - I hadn't realised when posting to OP @Seller_AVteysPitiEJq that it related to Letter post, sorry.

Don't think the OP is coming back - but both are on there.

However the CE Costanzo... was removed. The Shorted one was only registered in March 2025. Given some of their listings predate that - I would assume they at least originally had them under the longer version of the trademark.

That being said - it looks like their listngs now have the correct brand byline as they wanted.

Can you post the full notice that you received from Amazon? Have you opened a case with Seller Support? If so, also post the case ID number.

@Seller_mIRnuhdx7l5sN @Seller_z3k8APxGfbQEK @Seller_XUNeUuvrQDpgP @Seller_Huz6FT08OxHAR @Seller_TSXM2A5nxWSuH Can any of you check case details to privately let OP know which seller and in what manner they're alleged to have violated code of Conduct by?
