@Rachael110 some hosts have reported eventual success, after much persistence, getting some payment for damages; many hosts have reported no success. You can file a request for reimbursement and try. It sounds like your most urgent issue is getting this reservation cancelled and your calendar unblocked ASAP. I think you are extremely unlikely to get payment for the unused month, so I would focus on getting the reservation cancelled without penalty to you, by calling the US number and insisting on escalation until that happens.
