"Utterly disgusted"

My grandmother who is 93 came to A&E 3 weeks ago, she was left in A&E for 10hrs where on her hourly observations it was continuously noted that she was "still alive" she came in with a sore leg. Due to the utter unhelpfulness of the staff who refused to listen or take the time to examine her properly a blood clot formed and she has had to endure painful and what was ultemetly unecessary treatment. When finaly on a ward she has been ignored on every ward round, she has been left in her own mess for more than 7 hours getting more and more distressed. The staff do not listen, or show care or compassion, I will be making a formal complaint becasue the treatment recieved was so appauling.
