User is experiencing issues with two-factor authentication (2FA) SMS delivery when attempting to log in to their Meta account. Specifically, when prompted to send an SMS to a phone number and clicking 'Next', no SMS is received. This issue has persisted for months, and the user is unable to connect without 2FA. The user has verified that 2FA works after re-testing, but is seeking a reliable method to reach account support for similar issues in the future, as they were unable to submit a ticket through the web platform due to login issues.
