I am experiencing a critical issue with my Amazon account that is affecting all of my listings.

Yesterday morning, I had 300 units in FBA inventory. After approximately 20 sales throughout the day, I noticed that by the evening the available stock had unexpectedly dropped to 120 units. Later that night, the FBA listing became inactive with the message "Replenish inventory," even though there were still 120 units in stock.

I tried to resolve the issue by deleting the listing and using the "Fix stranded inventory" tool to relist it. However, after relisting, the inventory now shows as 0.

The missing FBA inventory does not appear in the 'Fix Stranded Inventory' section, but it is still visible in the 'Inventory Ledger' report

To keep the product available, I created an FBM listing. However, it displays the message: "This item cannot be shipped to your selected delivery location." — and this applies to all UK addresses. I also created FBM listings for other products, and they are showing the same issue. I sell exclusively within the UK, so this should not be happening.

When I try to create a fulfillment order, I receive the following message: "Your account is deactivated at this time. Please contact Support for assistance."

This leads me to believe that there may be an issue with my account itself, not just with individual listings or inventory. However, my account health is in perfect standing, with no warnings or violations.

Recently, I have been in contact with the vat-iba-verification@amazon.co.uk team regarding updates to the "Invoicing by Amazon" system on my account. It’s possible that these recent changes have caused a system glitch. I have already contacted that team, but they informed me they are unable to resolve the issue.

Could you please urgently investigate and let me know what is going on with my account and listings?

Thank you for your assistance.
