Oh! I feel so badly for you! It has to be painful and then the color, I'm sure, is very distressing. I let my sister attempt to dye my hair and she had had more to drink than I realized. I had to fly out of San Diego the next morning very early. I was afraid to open my mouth because I might quack instead of talk.

(January 1 through January 18, 2008)
L’Oréal Initiates Nationwide Recall of L’Oréal Paris Dream Blonde Bleach and Lightening Care Kit Due to Misprinted Directions
It says this:
All retailers have been notified and have removed the product from their shelves. Affected consumers, estimated at a few hundred, will receive a full refund for returned product.
I would certainly take issue with whomever sold it to you since it WAS recalled.
