"Still waiting after months"

I was initially admitted to A&E last year in September, 2014 with abdominal pain. A month later I had an ultrasound, following a consultation in December, 14 where I was told I will need to have my gallbladder removed. Still waiting after all these months for my procedure and nothing has happened yet. I really understand about the pressures the NHS can be like, although I don't appreciate being kept this late when comes to treatment.
