Not sure what is going on regarding Telus login but take a look at the attached screenshot. It's my name but not my account number and not my phone number. To the credit of Telus, yes, something did go wrong, they got that part right.
That's not really the issue. What is concerning is that somebody else's account number and phone number show on the screen which is a privacy issue. If it can happen to me, it can happen to someone else. If somebody has your phone number and account number, that is a probably a good first step for potentially fraudulent activity.
