Quest 3 hardware ban (Error 400, Subcode 2699019) on second-hand device — Need help opening a ticket

Hi! I need assistance regarding a Meta Quest 3 headset that appears to be hardware-banned from Meta servers. I recently purchased this device second-hand. After performing a factory reset and attempting to set it up with my personal Meta account, I encountered an authentication error. Checking the device logs via ADB revealed the exact error: Error 400 — Subcode 2699019: "Device Banned From Authentication: This device has been banned from Meta servers and authentication." The automated Meta Store Support website rejects my serial number, stating that support is unavailable for this device, which prevents me from creating a regular support ticket. I am the new, legitimate owner of this headset and had no involvement in whatever caused the ban under the previous owner. I can provide the serial number, photos of the device, proof of my purchase, and full ADB logs. Could a community manager please help me escalate this to the appropriate internal team or manually open a support case for investigation? Thank you.
