HELP!!!!!

[Mavrik]

Had a new clutch fitted two weeks ago, heres the problem, when engine is warm the car will not go into gear, or pull out of gear, you have to stop the engine to get it out of gear, and have to start it in first gear, also theres a vibration at top of pedal in the free play zone, but vibration goes when pressure is felt from clutch

Car has been back to the garage 4 times now, and they have adjusted the clutch cable every time

This problem is so bad now that my wife wont even drive that car, and garage is saying the problem is in gearbox (mainshaft or the flywheel bush they claim) but it was fine when it went in for clutch, although clutch WAS slipping, none of hte other problems were there

any advice would be appreciated

Forgot to add, car is a Polo 1.9CL 98 model (S plate) and has only done 32k
