You apparently don't understand how haircoloring works. It doesn't work like paint -- you apply it and you get a new color. Haircoloring is transparent. The new hair color combines with the existing hair coloring (whether natural or artificial) and that's the color you come out with.
If you try to put a dye on hair and the natural color simply overwhelms the new color, it may appear that nothing happened. I think that may be partly what's happening in your case.
It's not the brand of toner that will do what you want, it's what you do to your hair before the toner is applied!
