Meta account issue

My main standalone Meta account is locked behind SMS two-factor authentication. Meta SMS codes are not being delivered, and my carrier has confirmed there is no block on my number.

The account is still logged in and working on my Quest 2, and I have an active Meta Quest+ subscription. I cannot log in on web, phone, iPad or the Horizon app because SMS is the only verification method offered.

The normal Meta support flow is also inaccessible because device verification rejects my Quest 2 serial number.

I created this temporary account only to contact support. I need manual ownership verification and a reset/removal of the SMS 2FA method on my main account. I can provide the affected email address, phone number, Horizon username, headset serial and an active Quest+ subscription/ billing proof.
