"I feel let down"

I was recently sent to Frenchay to see a surgeon under emergency care, after having had surgery 3 months previous. The wound from my surgery has not healed at all and I lose approximately half a cup of blood a day and still have to endure excruciating pain. Firstly, I had to wait 4 hours to see a lady who arrived 90 minutes after me be seen first. I went to reception who told me "you didn't check in", when I know for a fact I did... The lady there tried to outright deny she had seen me. I was then told there were no doctors on the ward and I needed to wait another hour. I had taken a day off work to sit there... One doctor took me in to take a look at me who then said she wasn't experienced enough in this area to recommend what to do. I then had to get undressed for a second doctor, who told me they had no notes for my surgery... My GP also has no notes because they weren't sent there. So, nobody knows exactly what the surgeon has done and cannot comment whether I have an unhealed wound or a new problem. I was told I would be referred back to my surgeon. Two weeks later- zero referral. I called the secretary for my surgeon directly, explained the situation and she said she would book me in. She did... For 30th April. Does that sound urgent to you? I tried to call back and surprise surprise I left two voicemails and no response. I am suffering and feel failed by a shoddy system and staff who clearly don't listen...
