Can't get into my Nexora account after the 2FA code stopped coming through

Morning all. I’m locked out of my Nexora account and it’s driving me up the wall. Password is fine, but when I go to log in it says it’s sending a 2FA code to my mobile and nothing arrives. I’ve tried 4 times now. No spam folder obviously because it’s a text, and my signal is fine. Is there any other way in? I need to check my bill before it comes out.
