I launched a product in May 2025 - July 2025. It has been nearly ten months since then, but on May 9, 2026, I received an email from Amazon stating that my account had been suspended. I promptly checked the content and it was mainly due to Article 3 of the "Amazon Services European Business Solutions Agreement" and the Inappropriate Inventory Investigation Policy. However, during the two months of the product's listing, I did not receive any complaints or customer after-sales issues. As the account was suspended due to a supply chain change at that time, I promptly contacted the supply chain to reissue an invoice as per Amazon's requirements. But they asked me to provide a brand authorization letter. Since our sales method is brand manufacturer → certified distributor/ large enterprise → us → Amazon customers, we couldn't directly contact the brand manufacturer. During the sales process, my account rating was always in a healthy state. Regarding customer refunds and after-sales issues, I actively restored them. After I reported this situation to Amazon, they informed me, "Your account and any documents you submitted will be evaluated through our internal review process. Please note that currently we cannot share the specific details of this enforcement measure." Currently, my funds cannot be reflected, the account has been suspended, and I have no income source at present. My family had a big argument with me because of this matter. So, what should I do now? Who can tell me how to handle it?
