My Telus Unable to register for several months "THERE MAYBE A SYSTEM ISSUE" Your session has timed

Hi,

 i hope everyone is safe.

We made a business internet account about 5 months ago. 

when we try to register for my telus - https://www.telus.com/selfregistration  we get two errors, session error then sometimes system error
""THERE MAYBE A SYSTEM ISSUE"

then sometimes "Your session has timed out"
The info, (email account number and postal code) all match perfectly., we tried from different devices of course.

Its a telus back end issue, we called it and got no where, opened tickets, they still have not fixed it. Twitter help didnt go 

any suggestions ? thank you
