Davidchin,
Looks like your problem is more on your clutch pressure plate than anywhere else. If your pump fails, it usually fails all the way and you would have to tow your car back from Genting. If it jams on the way up, this usually shows signs of clutch plate failure. In your case, there is nothing much can be fixed except to change to a better clutch pressure plate. The springs are not pulling your pressure plate off the clutch disc. Inspecting the clutch plate would mean taking out gearbox to view it. DId your mechanic do that? It's not an easy job and not likely to be free.
