I do not think that it is possible, but you can try to contact the support
To contact the support you need to go to this page https://fizz.ca/en/contact-us, Fizz push you to find your solution, therefore, you need to search in the solution hub to your solution and only after 10 seconds that you are in a solution page Fizz will give you the chat bubble.
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.
Your can also send a message via facebook messanger https://facebook.com/fizzca and click send a message (this is a bit slower)
You can also fill a contact form from your account Once logged in, from the account panel go to My Profile → Contact Form (the subject are limited) and fill out the form and someone will email you back.
Your best option is to give to someone with your referral number, if you need one this is mine NPONZ (all letters).
With this code you will receive 35$ at your 3rd invoice.
