My OCI account hijacked.

Couple of years ago i registered Oracle cloud account. Domain (and email) used for registration expired and was abandoned.

I changed admin email to actual one before domain gone.

In some reason Oracle left initialy email as full administrative access. It is huge security breach.

Now someone registered my old domain and used it to gain full administrative access. He removed all users i added and kicked me off.

All my settings and cloud servers, payment info linked was given to that person. MFA was set but look like dont matter.

Dear commynity, what i can do? All my support requests is ignored.
