Account compromised and now can't delete projects on GCP i'm not part of it

My account was compromised. A malicious third party has created unrecognized projects to my resource manager (I did not set any organization)

I am blocked from deleting them because I lack Owner permissions, and I cannot open a support ticket under those specific project IDs due to permission constraints.
I’d need Customer Care to manually intervene, review these rogue projects, and remove/unlink them from my identity.

Can you help me or do you know someone to contact ?

AFAIK, the Workspace superadmin can always give themselves permissions on anything in GCP, including Owner, if necessary.

I did not set an organisation. So these projects are no part of one of it. I just want to delete projects into my account, i don’t get why it’s impossible to do that.
