Before placing the order, we confirmed with the customer whether his freight forwarder could transport the paints, and he said yes! Based on the customer's confirmation, we accepted the order! As the customer stated: after the goods arrived at his agent's warehouse, his agent informed him that the previous transportation channel was closed and temporarily unable to transport it! (Our transaction price was EXW, and the transportation issue was not caused by us as sellers. The customer repeatedly applied for a full refund on Alibaba's platform, which we refused. After Alibaba's platform intervened, they ruled that we did not need to refund, so the customer gave us a bad review) As far as we know, the customer's agent can transport this batch of paints, but the customer thinks the shipping cost is too high and refuses to transport it.
