Account Recovery Of My TikTok

I am having a serious account access problem with my TikTok account and I am unable to log in. I remember only my username, but I no longer remember the email address or phone number that are linked to the account, so I cannot reset my password or receive any verification codes. Because I do not have access to the registered email or phone, every login attempt fails and I am completely locked out of my account. I have not yet been able to reach TikTok support about this issue, and I have never made any purchases or earned any money on this account. I am using TikTok from Ethiopia. I kindly request that my account be reviewed and that I be provided with a way to verify my identity through alternative methods so that I can regain access to my TikTok account. I would like TikTok to help me recover this account even though I only have the username and no longer remember the registered email or phone number.
