I didnt see were to write the refferal code when I made my account and now I want to add it. How?
It is when you activate your mobile plan, if it is your fist Fizz service.
It sits in the Order summary page like this:
See the page for more details: https://fizz.ca/en/faq/how-do-i-invite-friends-to-join-fizz#2
But in that same page they do mention the following:
You can only add the code when you actually make your plan and activate it. So once you configure the plan before you submit you enter it in a specified box.
Important: You can only use the referral before you activate your first plan in the new account. It cannot subsequently be entered and applied. C
