Parkdean Resorts complaint: Soiled mattress

We stayed in a Arun caravan and everything seemed great but at bed time when we pulled out the sofa bed it was wet
there was also a large stain on the mattress I called the night staff I told them and when they finally came they told us they couldn’t get a replacement mattress until the morning as they needed to get it from housekeeping so they gave me 1 double quilt and suggested we slept on it I am 65 years old and was sleeping with my young grandaughter we had to take the cushions off the sofa and make a bed on the floor I hardly slept and had a bad backache for days when I complained in the morning a lady gentleman came to see us and replaced the mattress she come red it was at the bottom of the mattress but I had turned it that way I found her attitude rude, there was also alarmed old brown urine stain on the mattress also when they came to replace the Mattress they could see my grandaughter on the floor still asleep where she had rolled off her make shift bed that was still there, the same evening we opened the oven turned it on and found we only had a grill tray no oven trays I put some salmon fillets on this and closed the oven I could smell they wher ready so opened the door and the tray and fish where on fire the oven shelve had collapsed and the salmon was sitting on the flames causing a fire I reportythis and when they came again the same lady said it’s an expandable shelve and I should off pulled it out but how I’m supposed to know that wheni opened an oven the shelve was already in and who ever cleaned it last your staff didn’t put it back properly, I was given a £75 voucher to spend in the restaurant but we feel this was not sufficient for the misery off the first night lack of sleep and my bad back
We wheryalso told by the housekeeper and the gentleman that bought us the mattress that the night staff had access to get a new mattress the evening they came round and this could of been avoided .
