"A&E. Urgent care"

I visited A&E late Tuesday night with an elderly lady, she had cut her leg badly right down to the bone, we were shunted from A&E to urgent care. I insisted after 4 hrs a nurse look at the leg that I had personally heavily bandaged myself. Only then, after seeing leg was very bad sent back to A&E she has now been kept in hospital waiting 3 days for an operation to be told again today operation has been cancelled, disgusting service poor care for elderly pts being told emergencys come first. She was an emergency Tuesday evening and has been for past 3 days when will she get her operation ?? when her leg becomes gangrenous or she gets pneumonia? They have said operation tomorrow lets wait and see want people to know this hospital cannot cope , not caring, thought would be better under kings college but worse than ever ....
