Receiving messages of deactivation in 72hours

as a seller I would say Amazon don’t have justice for sellers because some of the brand owners made complaint on me for that I’m listing them products but actually the scene is Amazon allowing me to list these products according to my account performance and now I don’t have any documentation for resolve the complaint and my account health reached 40 and I’m receiving deactivation notification of 72 hours and no one supporting me from Amazon account specialist or customer support and I also contacted with brand owners to remove the complaint but I haven’t receive any single reply from them and now I’m sucked 😑😑 with the third class policy from Amazon because I’m not listing them product even I don’t selling them product and I’m just hunting products from the market and I’m listing it on but because of listing Amazon didn’t supporting me in this case
