I look orange after my spray tan!!! HELP!?

My mom and I went and got spray tans yesterday at Sun Tan City. The girl that worked there convinced me to get a "medium" spray when i always get light because my skin is naturally really pale. They ran out of this enhancer stuff so she said that it would be fine. It takes several hours for the tan to show up. This morning I woke up and I am ORANGE! It looks bad. Plus for some reason one of my arms is orange and the other is still white! Both of the undersides of my arms are white! I dont know what happened!!!!! How can I fix this???
