Yellow/orange banding on mid lengths (with picture)

[Robynjaexo]

Hi Geeks!
Wondering if anyone could help me, this week I have been trying to get rid of my yellow/orange banding in my midlengths but whatever I seem to do doesn't budge it at all! (Old colour from 7months ago underneath) This week my boss have tried bleaching the band 3 times with two tempts of 30% and last atempted using 40% to get it up to get it to a level 9/10 so I can tone it silver, the rest of my hair is silver/ash from a previous DIA light ash milkshake toner, is it a case of still trying to lift the band with bleach over time or going in with ash toners to kick the brassyness? Thankyou!

After bleaching 3 times I deffo wouldn't wouldn't bleach it again. A toner should kick out that warmth. Can't really see too well in the pic but if there's still orange present some parts may still be a level 7. Illumina 8/69 with 8/1 maybe a tiny bit of 7/81 too just to cover the orange.
