Desjardins

Your Desjardins banking account password? How was this asked?

I don't know of any Desjardins direct billing with Fizz. Fizz works with few prepaid card or some credit cards. Source: https://fizz.ca/en/faq/what-payment-methods-can-i-use

I'd call Desjardins right away with the phone number on your card or chat with Fizz. This seems highly abnormal.

To chat:

1. Go to a FAQ page e.g. https://fizz.ca/en/faq/status-services
2. Look bottom right for the big ❔ question mark in a green bubble.
3. Click it, options will be displayed
4. Choose 💬 "Chat"
5. Note: the bubble will only display the chat for a computer version. If you are on a cell phone, you must check "Desktop site" in your browser settings.
6. Submit your question with possibly a relevant screenshot or modem photo 
7. After that will be displayed the number of customers preceding you, to manage your expectations. Updated real time.

ALTERNATIVELY, try leaving a message on Facebook Messenger (https://www.facebook.com/fizzca), iMessage or Twitter private. The advantages of Fizz tool are the management of waiting times and the ability to print (e.g. PDF) a copy of the conversation for your records. Sometimes you can even leave a comment about your satisfaction with the conversation.

The WhatsApp way has been described in "How to contact Fizz on WhatsApp?" at https://forum.fizz.ca/en/discussion/comment/6568069

Probably a scam. Did you enter any info ? If yes, contact your bank right away.

Was it in a email? I think you can show it to Fizz so they can warned others
