As a seller of automotive parts, I recently sold a $50 belt to a buyer. However, the buyer requested a return and sent back a used/worn/old belt instead of the original product. I reported the issue to Amazon and filed a Safe-T claim, providing pictures of the worn-out belt as evidence. Despite this, Amazon refunded only $9, citing the belt’s “materially different” condition. I appealed the decision and was granted an additional $15, but subsequent appeals were denied. I find this arbitrary decision-making unfair, as the buyer now has a free belt while I suffer a loss of revenue. In my opinion, Amazon should reimburse me for the full sale price.now what should i do ?
