Garnier 7.40 Hair Dye Is Not What's Described, My Hair Ruined

The product ruined my hair color, and now I've wasted both my money and my hair. How can I fix this? They need to urgently send me the right hair dye to my address. Shame on Garnier for putting 7.40 on the market without proper testing! This situation needs to be fixed immediately, and if necessary, they should cover the cost of my salon visit. Hair is important! I can't go out in public like this! Look at this, how am I supposed to leave the room like this, your product didn't have such an explanation on it!!
