For several days in a row I have been trying to publish an ad with my own barcode. I am the owner of a registered brand, I am also registered in the GS1 system, and I can generate my own barcodes. But Amazon categorically does not want to let them through. I sent a bunch of requested documents (license, brand registration, agreement with GS1 ...). Each time the same ones, only in a different sequence. Each time a new consultant and a new cycle. We came to the point that they asked me for a document allowing me to publish an ad with my own barcode. This is only one product, and I have 1000 of them. Meanwhile, when I have sales on other sites, I am only engaged in proceedings on Amazon, and there are 0 sales. I can only regard such behavior as humiliation
