Parkdean Resorts complaint: Unsatisfactory holiday

We came to warmell for a break on the 28th June for 4 days, to be dissapointed in the fact that very little was open, and no prior notification untill 24hrs before departure, (which led to no cancellationrearagments being a option and this is not exceptable) the chip shop had nothing to eat from 6.30pm, non of the activities were open(skiing, boarding)Breakfast was not available mon-thursday, but available friday-sunday, our stay was monday-friday. The accommodation was lovely but the balcony was unstable, so I was dissapointed in the holiday, I’ve also booked with my family to come on the 20th-23rd August and I have my grandchildren with me, I’m a little concerned that it’s going to be as dissapionting and a waste of money. As a good will gesture could there be a upgrade of our accommodation, or money off food vouchers to make our stay alot more comfortable.
I understand the challenging times we have all been living through during the last 18 months or so, however we paid full price with the intentions we would get what we paid for.
I await your reply
