Answered question
What kind of company doesn't have phone support?
Fizz relies on community support. This is stated clearly in their webpage so they can provide the best possible rates. If there are big issues that need their attention you can contact them as follows.
Chat: https://fizz.ca/en/contact-us
Form: https://zone.fizz.ca/dce/customer-ui-prod/#/account/conta...

I agree that this method may not be the best fit for everyone. You would need to weigh your preferences between low prices and full service.

An all online company. They do have chat available though.
