Blatantly rude owner who neglects his visitors!!!!!

We are currently in unit 15 a chalet its been raining all morning. The chalet is upstairs. My fiance slipped and fell as there are no safety strips on the stairs. We went to speak to the owner Simon and told him we would like our money back so we can go home and take my fiance to the doctor. He is injured as his toe looks like it is broken/sprained and he has bruising and sc****s on his back. Simon was blatantly rude he said we should open our eyes and be careful on the stairs we asked him to place safety strips on the stairs he said no he cant. He also told us we are taking a fat chance because we want our money back . The lady in the unit next to us also slipped and fell on the stairs. There are no safety signs and no safety strips with grip on the stairs. The moment we asked for our money back the owner got rude. We have come to this resort several times before and spent money here. Only to be faced with a rude owner who has no concern for his guests. We are being forced to stay or we lose our money. I will never spend money at this resort again in future and cant believe the owners neglect to concern for his visitors. This is a liability claim. All we want is our money back so we can leave and go to the doctor. But he insits we are taking a chance when he saw the injuries with his own eyes.
