I don't know if it's a cable or hydraulic system but since you have to
pump the clutch it probably needs the clutch bled - it might also have a
leak - make sure the bleed screw is not leaking. Make sure it's not
leaking from the cylinder.

Otherwise, the cable is too loose - maybe the lock nut was not
tightened? Take it back to where you had the work done. It's probably an
easy fix.

Need a little more information. Who replaced the clutch?  What is the
source of the clutch parts?  Did they replace the pilot
bearing/bushing in the flywheel?
