"Formal complaint pending"

The treatment that my grand daughter received in the first instance was first class. Since then, it has been a disaster. Communication between departments seems to be non existent and a very sick little girl continues to suffer. I expect and demand that some serious action is now taken, as she is coughing up blood, not sleeping etc. As far as I am aware, thus far, only investigations into the cause have only been suggested. I look forward to your comments and a resolution to her condition before her health deteriorates beyond control. Should I not receive a response to my concerns very shortly, I will take this matter to the highest level possible which includes my MP. I look forward to your soonest response.
