Can anybody advice me, what the procedure is when a Independent Complaint is in with a Trust using the NHS Complaints Regulations 2009. I have been told by the chief executive that a full and thorough investigation is taking place which usually involves interviewing staff involved, however we are not due a response to this enquiry until 14th November and one of the members of staff involved in the complaint who would be interviewed has tried to contact us at home and left a message to contact them and also tried to contact others involved is this allowed?
