Today I received a return (FBA transaction) the package was not checked and opened by the Amazon return department and when I opened it I felt a strong corrosive smell that irritated my throat. I went to the GP and he was unable to help me and recommended that I contact the buyer to ask what he put in the box, but the buyer did not answer my question. I spent 3 hours explaining the matter with Amazon, but the help from Amazon is hopeless, no one was able to help me. Still I feel terrible. The liquid that was in the box was definitely not bioethanol because bioethanol has no smell (I have been selling boxes intended for bioethanol for 15 years and I know that the liquid has no smell). The buyer destroyed the product because he used a prohibited liquid, it exposed me to health damage and I don't know what to do next.
