If needed, you may clear browser cache first and you can try in private/incognito mode.
You need to contact Fizz customer service and they will create a ticket if the siuation warrants it.
We cannot contact directly to technical support.
The idea of this page https://fizz.ca/en/contact-us is to explain how you can access the chat bubble. If you do a search in the Solution Hub related to your issue and access the help page the chat bubble will appear at the right corner.
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.
