Tank Filler Pipe And Cap problems of the 2004 Nissan Armada

I attempted to place fuel in my 2004 Nissan Armada and was drenched with gasoline that backed up out the opening where the gas hose was inserted. This was unexpected and I smelled of gasoline all day. It was on my skin and clothing. This was dangerous and I am concerned about long term effects on my health. My gas tank was not full as it was 1/4 full when I tried to obtain gas. I was only able to get 20. 00 dollars worth of gas and the gas backed up and spilled on me. I heard a click as if the tank was full ,however it was not full. I also hear a hissing sound when I open the gas cap.
