Parkdean Resorts complaint: Health and safety

We are currently staying in a lodge 15 we have a window in the children’s room that does not close. Our 5 year little boy is autistic, he does not have a understanding of safety and rely on adults keeping him safe. The window does not close and has no locking facility. We arrived Monday 98 we did not notice this problem until today. You just assume that window door are made secure before guest arrive. We contacted out of hours left a message however we have not had any maintenance personnel come to check the window. I went to talk to staff on site explained the problem the staff member told me she would send someone right away. No one turned up. My husband had to make up beds in the lounge to keep our son safe. The door on the children’s bedroom does not have a locking mechanism leaving the door unable to close, should there be a fire this would leave the children at risk. We find it unacceptable that these safety features are not in place. Surely windows and doors are part of a safety check? The fact that windows are unable to lock potentially young children could fall out! This also has left us feeling unsafe, unable to leave the lodge unsupervised for fear of burglary. We would like a copy of Parkdean health and safety policy. Also we would like to know what safety checks are done before lodges are made available to families.
