Hair bleaching/ stripping a color?

Ok.. so I have deep brown hair (dyed that way) and i wanted the whole front of my hair to be purple..I went to Wal*mart and bought Splat hair dye in violet. Instead of doing it myself I went to my dresser and got my hair bleached (which turned out orange anyhow) then purple in it. IT WAS AWFUL!! Oh so disappointed !!! so now its faded to Purple at the roots and poop at the ends its DISGUSTING, I can't go to work like this in tuesday. LONG STORY SHORT::::::::> how do i strip this splat crap out of my bangs only...maybe even go bleach blond on it or whatever I can get! thank you kindly <3
