In May, I was invited to such a survey. Accepted, took. However, the promised Amazon gift card was not given. Sent an email to the person who invited me. No response so far. Why?
Sounds like some spammer got you to complete a bogus survey. Probably trying to fish some information from you.
Please be very cautious of free stuff online or "too good to be real" deals.
You should contact support service about that, try to go on this FAQ https://fizz.ca/en/faq/phishing-and-spam and click on the bubble to chat with Fizz.

The cake is a lie!
This survey was about to investigate user experience on using Fizz online account. During it, operated on a simulated Fizz page. It looked not a fake one. Really puzzled.
