I bought a mobile phone on Taobao. He didn't ask me to open it to my face, and he didn't insure it for me. The courier didn't say either. Now the mobile phone is broken. Who should I call? Or complain

When you buy something on Taobao, you must open it in front of the courier. Refuse to sign if there are quality problems. When he sells you something, of course, he won't guarantee your price, nor will he remind you to accept it in person. He wants you to sign for it quickly, so you can't blame him for the quality problem. Their delivery man won't take the initiative to remind you. If you refuse the visa, he will have to withdraw it, won't he? Now that things are like this, I suggest you keep the evidence, take pictures of all the damaged places, and keep the chat record with the seller when you buy it. First of all, consult the seller and see if this can help you deal with it. If not, contact Taobao customer service to try ~
