Facing a critical issue with my new product listing on Amazon. Entered the brand name 'PURIFY' for my hydrogen water bottle, but Amazon linked it to an old face cream listing under the same brand name. The assigned GTIN-13 code is now permanently linked to the incorrect ASIN. Multiple attempts to resolve through Amazon support have been unsuccessful, with responses from different associates causing confusion. Unable to create a new listing or change details due to ASIN assignment errors, brand registration constraints, and invalid product ID claims. Urgently seeking guidance and resolution to proceed with production. Any insights appreciated
