This is a public forum. Most of us here are users / customers like yourself.
You will have to contact Fizz support. Usually they will ask you to order another SIM card. Once you activate your mobile plan, you must contact them and they will refund you for the SIM you did not receive.
The idea of this page https://fizz.ca/en/contact-us is to explain how you can access the chat bubble. If you do a search in the Solution Hub related to your issue and access the help page the chat bubble will appear at the right corner.
If the chat bubble does not appear, this means that the number of sessions waiting for our answers surpasses our processing capacity. If that happens, send us a private message via Facebook Messenger or Twitter.
2 weeks? Yikes... You should contact fizz customer support for help regarding this issue. You can either chat with them online or send them a message and they'll reply back to your email.
To chat: You'll need to make sure you're logged in then go to Solution Hub and click on any of the questions (e.g. https://fizz.ca/en/faq/activate) After a little while you should be able to see a green chat bubble in the right-hand corner of the page.
To send them a message: Log in to your account, click on "My Profile" then "Contact Forms". Now "choose a subject" and "submit a complaint".
