There's just a ton of reasons it's not clearing - but most of all it takes time. I would not expect a week to do it. When I clear meads I expect weeks/months for them to really clear well. You will absolutely hear about people that say their mead clears in a week. I don't know if they have lower expectations than I do, or if I'm just living wrong.
When you say you racked and added sorbate - was it done when you did that? Or did you expect the sorbate to stop the fermentation? Because it will not stop an active ferment. A better way to go is to be sure the ferment has stopped, see the mead drop clear, and then worry about stabilization (and additional sweetening if desired.)
Anyway, there's a lot of your story we don't know but now you have additional information. Share some more information back if you want more thorough answers. Knowing more specifics about your process will allow us to help you more.
