You can always reach them on social media facebook or twiiter. Response times are usually fairly quick via those methods. As for the email form not working. Make sure you're not copying and pasting in the mail form or using emoticons.
Looks like the email is for Mobility inquiries, and requires a login, so it is checking your services to determine eligibility to continue.
I, too can access the form. Have you an account set up in 'My Account' with Telus?
The only other ways I see to not wait in the phone queue, are to use Chat, or send a message through Facebook or Twitter.
You've got my attention. I tested the link you gave. Seems ok. Do you have a portal account set up? As far as the fiber link, I need your tel number to run tests on your circuit. Please provide the info by PM only. Never give your account details on the open forum.
