1999 SAAB 9-3 repair Question Clutch is stuck

I bought this car yesterday from an individual. I was assured that the clutch was brand new. The master cylinder was replaced less than a month ago. All leakes etc, had been repaired.

I did not make it home before the clutch pedal stucjk the the floor and the clutch would not engage. I had it towed to the company that fixed it, and they say it is not the master cylinder (which is under warranty) but another leak.

I think these guys do not know what they are doing. They have worked on this car twice, charged over $800 and it is acting exactly the same as it idid before they ever touched it. What I want to know is if I add clutch fluid, can I drive it to a different shop safely? Are there more than one type of clutch/transmission fluids on this car?
