The great god called for help. There is no signature on the courier. I arrived this morning, but I didn't take it home on the spot, only to find that there was something wrong with the quality. You can send it directly in the afternoon. This practice is very embarrassing. Although there is no signature, the express delivery has been reported and you have received it. So the express delivery will not be refunded to you for free. The seller already knows that you have received it. If it is a quality problem, communicate with the seller. If it's transportation damage, negotiate with the courier, but it's too late. You can return the goods due to quality problems or ask the other party to pay the freight. .
