Why Do I Have Exposed Nostrils?

Before rhinoplasty I had a long, strong nose. I was looking to have a more slimmer nose and a bit more of projection on the tip. I ended up with a short, stubby nose with exposed nostrils and a bulbous tip. Why did this take place? How can it be corrected? What needs to happen to get rid of the exposed nostrils? Should I have to pay again? This is not what I requested and I clearly had a better nose before. Now I am scared to use the same surgeon as the result is what I had asked for.
