My Amazon store received a negative feedback in February, but I refunded the customer as soon as possible to protect their rights and interests. We have changed our transportation process to improve the service, but now it is late March, and my store still loses the qualification of advertising activities and cannot sell products, which means that I cannot improve the store problem. I need to be able to advertise. If we can't sell, how can we improve and prove that we've made the necessary changes? I need admin help, please check our account to see if we can get help from someone at Amazon so we can resume the sale. @Manny_Amazon @Rose_Amazon @KJ_Amazon @Danny_Amazon @Sandy_Amazon @Tiff_Amazon @Blake_Amazon @Quincy_Amazon @Emet_Amazon @Roberto_Amazon
