Hi @Karalaini0, As @Mike-And-Jane0 mentioned, for cancellation of your booking, you will need to get in touch with either the Host or Airbnb Customer Support team. Have you reached out to them yet with your concerns?
If you are looking for help on how to contact the Support team, you can do so by exploring this link: https://www.airbnb.ca/help/article/1542.
I am also sharing a link to the article that can help you with a step-by-step guide on cancelling your reservation for a stay within the Airbnb website/ App: https://www.airbnb.ca/help/article/169.
Keep us posted if you still need any help with this!
