"Unsatisfactory care involving a head injury"

I waited 20 minutes at reception, then she took my details and told me to wait for the nurse. I then waited 45mintues to see the nurse, they were very abrupt and was chewing gum which I see as unprofessional. I was then told to wait for the doctor. I waited 1hour and 30mintues to see the doctor after watching 5 people go in to see the doctor who had arrived after me, baring in mind I had suffered a head injury! I then saw the doctor and took my injury not a seriously as it should've been. They have me some tablets which I had to wait 20mimtues for and then told me to go home, even though I had passed out before and after taking the tablets. I don't see this as good enough care
