"Disgusted and disappointed"

My 18 month old daughter was referred to ENT following 12 months of repeated viral infections, chesty wheeze and enlarged tonsils. Our first visit took place on the 22nd June we walked into the room to not even be introduced to the doctor seeing us who then proceeded to ask me why we were there and did my child have sleep apnea, I tried to explain the situation and that she had had blood tests, chest x ray and sleep study carried out but the only thing that could be found causing the issues was her enlarged tonsils, they told be to get her out of the buggy and looked in her throat at which they said there was nothing wrong and said her choking episodes were out of habit and nothing else but that they would arrange appointment for an x ray on her nose for her adenoids, whilst waiting for the x ray appointment to come through I received a letter from said doctor which stated that she had a grade 2-3 enlarged tonsils when asking my GP and also checking on NHS website found that this meant her throat was 50%-75% obstructed by her tonsils, we then got a phone all stating that there would be no appointment for x ray and we should have been told to just attend hospital x ray department, I asked that the consultant phone me and explain why they didn't advise us of this and to apologise for their mistake this was not done, on the 6th July we attended a follow up appointment for results of x ray to be told it hadn't been looked at as it was not done in time, I asked the same doctor why they hadn't called like I had asked and also why they told me at the last appointment that nothing was wrong and then wrote a letter stating something totally different. They refused to answer station I was entitled to a second opinion if I didn't like theirs and that I was being very rude and aggressive at which point I told him they were a disgrace to their profession and the NHS. This now leave me in a very difficult situation as we are no further forward in finding out what is wrong with my child and how long it is going to take to find out very little confidence in the NHS and especially the ENT department.
