Complaint about the attitude and handling results of after-sales service in Apple's official website in China.

In December 2021, I ordered an iPhone 13 Pro Max on the official website of Apple and purchased AppleCare+ service. Within a year and a half, the phone had serious hardware malfunctions, automatically shutting down and restarting every minute in a continuous loop, making it impossible to use normally. Therefore, I looked for Apple's direct store, Apple West Lake, in Hangzhou, China, for paid repairs. This repair took me a month's time, and due to the malfunction, all of my important data couldn't be backed up. After the repair, the phone's malfunction became even worse, and it couldn't even turn on. I am dissatisfied with the processing speed and results of the Chinese official website. My demand is a full refund or a replacement for a new machine, and I hope that Apple headquarters can intervene and solve the problem.
