Ugh. I need HELP! (Too blonde roots)

Here's a quick story. i bleached my hair, and the ends (b/c i ahd a dark hair dye on them a year ago) came out slgihtly darker. i added a toner and it helped a little but you could still see the band of color.

So i was told to bleach it again, and put it on the roots first. Which I did. so after letting it set in for a bit (30to 40) we added it to my roots (as I was told). I sat there for another 10-15 minutes, and even though I watched my hair didnt see a change. I rinsed, and now my hair is s soft/gold blonde (which isn't so bad) but my roots are white blonde.

What do I do now? I was told to add a semi-permanent to my roots. I happen to have one bottle of semi left by Beautiful Collection and it's b10N Champagne. Level 7/Base Neutral. Should i add this to my roots? I'm at a loss. I think my hair looks horrible. i dont understand why it did this. It's never happened to me when I dyed my hair blonde before I had kids. PLEASE HELP
