what is the address of return to fizz

Hi

You do not need the address. Here are the instructions from Fizz

How to mail your Wi-Fi modem to Fizz headquarters:

1. Put your Wi-Fi modem in a suitable box. What size box do I need?
2. Download, print or write down your return ID number, which was on the final step of the unsubscribe process. Canada Post will need this number to print your free return label. How do I find my return ID number?
3. Drop your boxed Wi-Fi modem off at the nearest Canada Post deposit location. Find a deposit location

There are two ways to find your return ID number:

1. In the confirmation email you received when you unsubscribed from Fizz.
2. By returning to the Fizz unsubscribe process. Once you’ve unsubscribed, you’ll be able to access a shortcut to your return ID number.

To find your return ID number in your Fizz account:

1. Log into your account and go to Manage.
2. Click on Unsubscribe.
3. Instead of the unsubscribe process, you’ll see a button that says: Cancel my unsubscription.
4. Below this button, click on See instructions for returning my Wi-Fi modem.
5. Here you’ll find return instructions, your unique return ID number and barcode.
6. This barcode will allow Canada Post to print your return label for free.
