My hair is YELLOW!!!! :'[?

So last year i had burgundy hair, i let it grow out, got it cut, and dyed it light brown. that was a while back and know i wanted to go blonde...like almost white. So I bought a raw beyond bleach kit. ...i didnt have enough in the box so i just did as much as i could....it turned spotty. like white, blonde, yellow, brown, orange. and i was like wtf!?!? so i bought a super blonde bleach kit ans did it over again and it all the same color now [mostly] but its...yellowish. I wanted white....i dont want to kill my hair even though it takes alot to do that...but still. i wanted white hair and i got yellow :[ How do i fix it?!?!?
