You can chat with them

Try with this instructions, I tried now and I was able to have the chat bubble.
.
- Go to this page https://fizz.ca/en/contact-us, if you are not connect login
- The business hours: every day from 8 a.m. to 9 p.m. (EST).
- Wait 5 seconds for the bubble icon to appear at the bottom right of the browser and click on the icon to chat with support. Try a different browser if you have issues getting the bubble to appear.
.
If the chat bubble does not appear, this means that the number of sessions waiting for our answers surpasses our processing capacity. If that happens, send us a private message via Facebook Messenger or Twitter.

Sorry no support by phone, just https://fizz.ca/en/contact-us
What's the problem

Try by messenger, it's going not to bad. You normally get a answer by the day.
