Introduction: We have been selling our own privately branded product on Amazon since 2015, and we are the only authorised seller of our brand. We are also brand registered.

In the run up to Christmas, we are currently running a Prime Exclusive Discount one week at £29.99, and then a 7 Day deal the week after at £27.99.

A few days ago, we noticed an unauthorised seller had won the buy box on our listing at £24.99. As we have done in the past, we logged into Amazon Brand Registry and reported a trademark infringement as the seller was listing a counterfeit product.

Whilst the brand registry report was 'Under Review', the unauthorised seller made a sale at £24.99 (5 items were showing available, and now there was 4).

After a few hours, the brand registry report was 'Accepted' and the unauthorised seller was removed from the ASIN completely.

Today, we logged into Seller Central to find that all of our current and future deals have been suppressed and Amazon are wanting us to match the price of £24.99 as this is now the lowest price in the last 30 days!! Due to already thin margins on this product, we would be at a loss selling for £24.99.

Has anyone dealt with this before, and if so, is there a way to resolve this? We have opened a case with Seller Support but keep getting a generic response advising us to 'Report Abuse' on the listing itself.

Our sales have ground to a halt, and ironically, we have just sent a huge replenishment order to Amazon FBA based on the forecast they emailed us (FBA Replenishment Alert).

Any advice would be greatly appreciated as we are really suffering at this time. Thank you in advance.
