I ordered one sim card but I received two by errors and got charged twice

The chat bubble was not working yesterday evening. Fizz had some technical issues that appear to be solved right now.

Give it another try. 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
