SHEIN Won't Let Me Change My Phone Number Without Logging In

I have a SHEIN Australia account that I can no longer access because the verification code is sent to my old phone number, which I no longer use. When I try to log in, a “Verify recipient’s mobile number” window appears and the code is sent to my previous Australian number ending in 97, so I am completely blocked from entering my account. I lost access to this phone number around early February 2026, and I have not placed any orders on SHEIN since 2024, but I still want to recover my account. I cannot reach any phone support or contact a number for SHEIN to fix this situation, and there is no option on the screen to change or update the mobile number without first logging in. I request that my identity be verified with alternative methods such as email or other security questions, and that my registered phone number be updated so that I can regain access to my SHEIN account as soon as possible. I would like SHEIN to assist me in recovering my account and ensuring I can log in without using the old phone number that I can no longer access.
