Error code 5995, matching error, someone else has used same EAN

Hi all

I have 7000 units in FBA of a key product. Suddenly the listing became in active and i was advised to delete and relist. I did that and have been unable to relist since. Its taken 2 weeks and probably 30 or 40 emails back and forth with Amazon to establish what the issue is - someone else is using my EAN. The problem is that this is an old listing set up before GS1 was made mandatory and my EANs are not from GS1.

I am where i am. But what do i do to save my stock and my listing with all the reviews?

The stock is currently ‘stranded’ and my understanding is that after a certain amount of time, this stock will be sent back to me at a cost of £0.40 per unit. That’s an excruciating £2800 in total cost, then i have to manually relabel every single box is the FNSKU changes. and send it back to Amazon.

Isn’t there an easier way? I am able to use the ASIN to set up my old listing but with a different SKU. Can i ask brand registry to update both the EAN (to a GS1 one) and the SKU to re-link the stock?

My suspicion is it took so much effort to get out of amazon what the problem is because it is effectively their fault by not having adequate systems and controls in place pre2017 meaning that people like myself are suffering the consequences of a late change in EAN policy. By avoiding saying what the problem is on paper (they only told me on the phone), i believe they see this as avoiding legal risk. Its not acceptable, though, to destroy people’s businesses like this.
