Hello @Kirsten234
firstly this is not Airbnb we are a community of hosts and guests like yourself who provide each other with help.
I am so sorry to hear a guest severely damaged your home.
the important thing in this case if you want to make a claim against Airbnb's guarantee is to follow the procedures they have outlined in their T&Cs for doing so (go to Airbnb Help and search Airbnb Guarantee)
you don't actually need to speak to Airbnb to initiate the claim and start the process
1. you need to collect photographic and video evidence of the damage
2. you need to contact the guest via Airbnb to flag the damages, send them your video and photo evidence and tell them you are lodging a claim for them to pay for the damage with an approx cost (you need to do this before your next guest checks in)
3. If the guest ignores you or denies the claim contact airbnb who will investigate the claim
3. I'm not sure whether you have got quotes for repairs yet if not get these and receipts for costs of any goods that need replacing
