Two Factor Authentication

I enabled two factor authentication on my account via Ring.com to send text messages to my phone. After I enter my phone number, and press continue, I never receive a text message.I tried to change the number associated on my account to my new mobile device and still no message is received.I then added another user to my account with a new phone number and log in and the text message authentication work fine.I tried to call Ring support two days ago and they said their authentication service was having a technical problem. Well, I guess that is not the problem as I proved it was working via the second user I added to my account.Any suggestions?
