How do I resolve refused credit card when card is good to use?
Hi Steve,
You can use a Visa or MasterCard credit card to pay for your Fizz plans.

I'm having the exact same issue today with no help from CSR on chat except "try again and wait 2 hours"
Which card are you using?
I have seen other customers are having issue with specific cards as well (notably Desjardins Visa). It seems that some cards work better with Fizz's billing system than others.
To get your service restored asap, is there another card you can use?
Some prepaid cards like Koho will work as well.
Sad issue, I changed my credit card yesterday without any problem
Fizz seems to be very picky with credit cards. You may be out of luck. Contact Fizz support
