"I will be making an official complaint"

Where do I begin? I came to A&E on the midnight of Monday/Tuesday I waited nearly 6 hours to be seen despite having told the nurse I had chest pains. After I was seen I was sent to X-ray, after which I was told I would be staying I'm hospital. I them waited another 6 hours before being moved to the clinical decision unit, this was in itself is a terrible ward, dirty and down right disguising. The staff on there where terrible, rude and inconsiderate. At one point one of the doctors who upset me was discussing my entire medical history which had no relevance whatsoever with his medical team in full ear shot of the entire ward saying I may add some extremely worrying things for a doctor. To be saying about a patient in his care I was made to feel like he was not only making a fool out of me but like I was wasting his time both him and his team treated me with nothing but disrespect. Other patients could here my medical history from childhood and what he was saying he thought about myself. I was told that you are not meant to stay on cdu for longer than 24 hours I was kept there for 72 hours then moved at 2am! To a different ward It was what I heard on the hand over sheet that alarmed me to a serious error in what this doctor had been saying about me something which he lied about me having which to me was very worrying what else do doctors lie about? I shall be making a request to my medical notes for this reason.
