2000 Toyota 4Runner Master cylinder

I have a 2000 4runner that I just had a new master cylinder put in it because the clutch wouldn't pop back up after changing gears. Now that I replaced the MC -
1) the clutch never comes all the way back up (I have to pull it up with the toe of my shoe)
2) the catch point is very low.
3) I really have to push it to the floor just to get it to changes gears.
The guy I took it to is a good guy and gave me my money back but he still can't figure out what's wrong and how to fix it.
Pls help if you can.
