Unable to update expiring credit card on file

Hello,

My credit card to pay for my streaming services (Disney, Netflix, etc.) is about to expire at the end of this month. 

I tried logging in online, but I got a new phone in the last few months and the log in verification (using either the app or web browser) is being sent to my old phone, which I no longer have access to. I have a backup email set up, but when I use it - no emails come through. This means I have no way to log in to my Telus account. 

When I search for a phone number or online form to fill out to ask how to change my credit card - the online form says that it is not for billing questions and I will not get a response if it's a billing question. There is also no phone number for billing questions.

This means I cannot log in to my account, cannot phone anyone, cannot fill out an online form, and I have no way to get ahold of anyone in general. Is it not possible to update my credit card in this situation?
