Unauthorized Seller Alert: New Seller Selling My Private Label Product

Hello Fellow Amazon Sellers,

I started selling my Private Label product on Amazon about two months ago and have been monitoring its performance closely. Today, I received an email alert notifying me that a new seller has just launched and is selling my exact product. This was completely unauthorized and, obviously, quite concerning.

What immediate steps can I take to get this unauthorized seller removed from my product listing?

What is the best way to reach out to Amazon to resolve this issue?

Are there any proactive measures I can implement to prevent this from happening again in the future?

I would greatly appreciate any advice or experiences you can share regarding this issue.

Thank you for your time and expertise!
