I remember you asking about this trip a week or so back and how you were going there as a carer with people in wheelchairs.
Sorry it all went wrong, does not sound good at all.
Here is the Contacts detals for Warners.

I would send an official letter by post direct to the "Manager" at Gunton Hall.
I would also send a letter by post to the owners of Warners who are Bourne Holidays Ltd, their address is at the bottom of the web page.
If you make enough "fuss" they may give you a refund, or maybe vouchers towards your next holiday (assuming you want to stay at Warners again)
