This is because your refund application is not supported and cannot be judged. As far as your description is concerned, you didn't reject the goods after signing, and thought it was "too dirty to describe". When Taobao is involved in the normal handling, you need to submit the red stamp certificate of the courier company. If it cannot be submitted, this refund application will not be supported.

Because the credit record is considered good by Taobao, Taobao pays you a sum of money compensation, which is paid by Taobao. If the rights protection is not established, the seller will also get the payment.

There is no such thing as punishing the seller, and it is not said that you will punish the seller because of your personal preference. Fund compensation means that your personal credit is good and not punitive. Bad sellers pay or not. If your credit record is not good enough and Taobao doesn't pay the fund, your refund application and after-sales rights protection can't be established, let alone the question of who pays.
