Bathroom wall repair

A guest slipped and smacked their head into the bathroom wall of the house I'm renting, and now there's a big adult head sized hole in it with a crack leading down. I'm looking to have it repaired if possible, though I think the whole wall panel will need replacing since it's that shiny bathroom wall stuff. I have no idea who and how to go about getting this repaired before I my landlord sees. Please help mee
