Meta refuses to let me delete my account

Hi, sadly, when trying to delete my account, the POST request to /api/graphql gets answered with the following information

"dnd_error": {
"__typename": "XFBFXDnDGenericError",
"title": "Da ist etwas ist schiefgelaufen",
"description": "Bitte versuche es später noch einmal.",
"primary_button_label": "Schließen"
}

There is no visible error in the UI. I also can't seem to gaslight the support AI slopbot enough to let me talk to an actual human. Every support article just puts me into a loop that makes me repeat the exact same steps that keep failing since a few months. Does anyone know about any way to exercise my GDPR granted right and have my PII deleted, without having to send a actual letter to an US address?! 

Thanks
