Our only negative seller feedback is from a competitor. They purchased a product from us and then upon receipt immediately left us negative feedback questioning the authenticity of the product. As we thought this was utter nonsense and a bit odd as they hadn’t even contacted us to complain, we investigated and found that the buyer was also selling on our listing and had left the same negative feedback on all the sellers that were selling the item cheaper than them. A day later Amazon blocked us from selling that item, we appealed by providing supplier invoices etc, and Amazon accepted our appeal and allowed us to list the product again. We haven’t though as that underhanded competitor is still selling that item and we don’t want to expose ourselves to further negative reviews from them. Interestingly, none of the other sellers that received the negative feedback are selling that item anymore either so the competitor in question has basically just bullied their way to the buy box.

We contacted seller support in May to complain as it was our understanding that it was against Amazon policy to leave reviews for competitors and the status of that case is “transferred”, and has been for the last 4 months. Our negative feedback remains so we’ve just left a comment against the feedback explaining it from our point of view and we moved on, hoping that one day Amazon will respond to our case.

So to answer your question, you could contact seller support but from our point of view, we’re not sure they’ll do an awful lot but if they do, don’t expect it to be resolved quickly.
