I am Unable to login my account

Summary: Request for Help with Restoring My Oracle Cloud Account Login

Content (required): I am writing this post because I am unable to log in to my Oracle Cloud account. After investigating the issue, I discovered that my login email address had been changed from roshanpan01@gmail.com to any others mail address without my knowledge. Although I have already sent an email to network-contact_ww_grp@oracle.com, oraclehelp_ww@oracle.com, c2csupport_ww@oracle.com, oracle-acct_ww@oracle.com I have not received a response.

My account was taken over by someone else, and I have no access to the account email or password, both of which were changed by that person. As a result, I can't reset my account password.
