I used the trust's website feedback form to point to this Blog and this is their response!
Thank you for using our website feedback form. I have spoken with staff in the Chief Executive's office and the letter you refer to in your message has not arrived. Could you tell me the address and date when this was sent so that we can look into this matter further. It would also be appreciated if you could forward a copy of the letter again.
Thank you for help in this matter.
