Parkdean Resorts complaint: Unclean caravan

Arrived at 5.30pm found our caravan (26 Plaza) but the red sign was on the window which meant do not enter, I walked to the reception and told a member of staff about the red sign I was told sorry about that someone forgot to turn it over to green, back at the caravan told my husband and daughter inlaw that we could go in as it had been cleaned on entering my daughter inlaw and myself noticed bread crumbs on the kitchen work services there was also grease marks all over the cooker and to top it all the carpet had large stains near the seating area.
Our party considered of 4 adults and 2 children 4 5 yrs old my husband and son took the children to the play area while me and our daughter inlaw thourally cleaned the main body of the caravan finishing of wiping all areas down with sanitiser wipes.
The next day I reported this at the reception and was asked did I want the cleaning supervisor to clean the caravan I informed her what we had done, then asked for our welcome pack which should have been in the caravan on our arrival.
I have posted two reviews since returning home and two duplicate replies from parkdean which I have copied and pasted below.

Thank you for taking the time to complete this review. We aim to clean all of our accommodations to an exceptionally high standard, it is disappointing to hear that you felt this wasn’t the case. We do hope that you ly raised this with our Reception Team, to allow us to rectify this for you. Naturally, we are sorry that the issue arose initially. We hope that your experience does not deter you from re-visiting any of our 67 holiday parks

I have a friend that works at a parkdean site in the lake district near our home town and she told me what to expect when I booked a parkdean holiday ie: cleanliness of caravans, welcome packs in caravans on arrival along with a comments form and a supervisor visiting caravans to ask if everything was ok.
I would have thought that all parkdean sights are run the same but sadly this is not the case.
