Parkdean Resorts complaint: Cleanliness of caravan

We stayed at Southview parkdean resorts, Skegness. Stayed in caravan 24 poplars.
We paid an extra £40 to bring along our pet dog Blue. The booking was under the name Wayne Shannon. Booking ref: 8589093

The caravan was absolutely disgusting to a point where we had to ask for extra bed sheets to cover the sofas as they were just disgusting!!
The bathroom floor and shower was dirty, the floor by the fridge and at the side was black with thick dust and grime, the carpet in the lounge area was full of other dog hair, we have a black lab so when we swept the floor and found other dog hair in the pile you can imagine our disgust! The sofa was full of stains and felt dirty…my children refused to sit on them for the first three days until I got the bed sheets to cover them!
To top all this off my 8yr old daughter brought a packet of tablets to me which I was horrified to see they were a full pack of diazapan tablets. You can understand my absolute horror of this as we could have been calling an ambulance and the park being sued for negligence. We belonged to a party of 16 and everyone was horrified by the cleanliness of the caravan and then the diazapan tablets which I gave to reception to dispose of safely!
The grill door constantly fell off and the kitchen floor needed washing. One of the small bedrooms (nearest to the kitchen) had crisp all under the bed upon our arrival. I have is experience in the housekeeping industry as a supervisor for Hilton Hotels and BMI Hospital in Kent and I can assure this caravan would have not passed any inspection of mine (especially with Covid still around)
I spoke to the manager (a man) he apologised and gave us £60 worth of vouchers for us to use in the restaurant…we go to the restaurant and find that the kitchen had virtually ran out of food and we were not allowed to use all the vouchers at the restaurant only £50 worth, as a family of 5 and a party of 16 we spent an awful lot of money with you.
We have not been together as a family since the beginning of Covid, this completely ruined our time away with the family and children. We ended up having to stay out of the caravan most of the days and visit my parents who were on the touring part for most of the stay as my children did not want to be in the caravan as it was that disgusting.
