Cannot get codes on SMS

I’ve been trying to log into wow now since 12pm (12/11 2019)
but when i choose to get sms code instead of authentication, i dont get the codes. I’ve written multiple tickets to blizzard but no help. I changed my number yesterday and it worked perfectly, even tried to re log just to see if it worked and it did but today at 12pm when i tried logging in and sent for a code NOTHING happens, i try resending and resending but nothing happens. I paid for this so i expect to be able to play! Blizzard FIX IT!
