Xiao er urged the seller in various ways, but he could not force the delivery, and there was no guarantee that Xiao er would say that the seller would cooperate. You can judge whether the seller has received the message through Ali Want Want and carry out the follow-up operation. In the Want Want message, it will show whether the seller has read it. If it reads it and still ignores people, that is the seller's service attitude. In view of the fact that the seller may still need to be contacted for follow-up problems after purchase, it is suggested to apply for a refund directly and replace the seller with higher credibility. In this case, if you don't intend to refund, you can only wait and complain after the transaction, and you can claim a 5% penalty on the grounds of delayed delivery. What you can do now is either apply for a refund, or complain to him later and threaten the seller. It's no use looking for Taobao customer service now, unless you want a refund.
