My iPhone 6 phone number for iMessage and FaceTime is no longer activated?

I recently updated my phone to iOS 11.0.3, and after doing this update I found that the iMessage and FaceTime wouldn't allow me to use my number to iMessage and FaceTime anyone, and it would only allow my iCloud email address to do iMessage or FaceTime. I've called Apple Support multiple times and I did everything that they told me to do, but it still isn't activating. This has been going on for a week, and I even did a restore of my iPhone as I assumed that would fix everything, but so far it hasn't changed anything. Is there anything else that I can do, or should I just take it into the Apple Store.

Did you got to settings-message- send & receive and enter your number?
