Answered question
I already read: https://fizz.ca/en/faq/how-do-i-unsubscribe-from-fizz-hom...
I have no such option as "Unsubscribe" in my Internet plan.
Can someone point me in the right direction?
I'm guessing you are within 48 hours of your plan renewal. Fizz does this for the mobile plans, but I think it should not apply to internet plans.
Under these circumstances, contact Fizz support. They should be able to help.

Unfortunately in that case you will need to contact Fizz support either using the chat function on the help page or contacting them using Facebook Messenger (The preferred method).

I am sure by now you have unsubscribed. Going to My plans --> Manage --> Unsubscription
Btw Fizz changed their moving policy. You get to keep your beta pricing when if you move out.
