Smule Won't Let Me Back Into My Old Account Even With Matching ID Information

I can no longer access my old Smule account with the username "Omeralyu," which I created a long time ago. I no longer use the phone number linked to the account, and I don't remember the registered email address. However, the first and last name on the account match my own identification information.

I don't want to lose my records and history from my old account. I'm requesting that my account be reopened and restored to accessible status, with the necessary security verification carried out using my identification information.
