we have sent the goods as requested by the buyer. This is the tracking number 1Z693V0R0403861648--UPS. My store has been officially certified by Alibaba and TUV, and our company sells genuine products. And according to the POD (proof of receipt) provided by UPS, it shows that the buyer has received the goods. We have no way of knowing why the buyer initiated a refund after receiving the goods. Even so, we have worked with Alibaba to refund the customer. We believe that as a company with important influence in Alibaba, we have done our best.
