Parkdean Resorts complaint: Overall stay

We paid for an up grade on our stay and to be honest I can’t see where the up grade was, we had no hoover, no toilet brush and the light out side our caravan wasn’t working, I informed security and reception for 3 days and eventually they came out and a new light on. The outside steps weren’t great one dipped in the middle.
On the first night our 15 year old daughter and her cousin were chased by a strange man which once security had been out checked the cctv and police informed with a report made by myself to them one of our entire day’s were ruined no one followed up to see if they were OK.. The third day we were there the police came out and said they see how terrified the girls were in the cctv.
In previous years we haven’t had an issue but this we were extremely disappointed in our stay, no concern from staff for the girls and the so called up grade was a disgrace.
I would like either part refund or money off our next stay.
We took our 3 Foster children along with us and they were very upset..
I would like this to be resolved ASAP
Caravan was M16 Mallard way
