Parkdean Resorts complaint: Cleaning complaint

We arrived at the caravan and the green card was showing so we entered, there was a smell in the caravan and we noticed the bathroom had been re sealed and there was still all sealant in the shower and on the floor? At this point I phoned a complaints line but was told to call reception as we are already there. I left number etc but received no call back?
We were passing later on and we were told bag cleaners entering our van that it hadn’t been covid cleaned???
My partner had made beds and we had unpacked into a dirty caravan?
The cleaner called a Parkdean rep who attended and although apologetic offered us fooddrink vouchers!!! This although we appreciate the gesture is not acceptable especially after paying £600 plus pound for a bog standard caravan and all what’s happened since we arrived!
I am basically disgusted that this has been allowed to happen and all with a 3 year old toddler in toe!!
We are now being told the shower os not yet fit for purpose?
To think this has been allowed to happen when covid regulations are still in place in this part of the country is alarming especially for a company of this size.
