1992 Ford F-150 very little clutch pedal resistance when dep

Vehicle taken to shop for clutch replacement. Clutch was smoked but pedal action was normal, you could push the pedal in and it would spring back. But now after a new clutch kit has been installed along with a new clutch master cylinder. The concentric slave cylinder was not replaced because it was not leeking and in good working order. The tech working on my truck has bled the system over and over and over again but cannot acheive proper pedal action or clutch operation. Now, the pedal when depressed goes down with only moderate resistance, it will stick down slighty or slowly come back up. It will not go down and spring back like it should. Now it turns out that the shop owner is having legal problem along with employee problems and me and my truck are stuck in the middle. My truck has been at that shop for over three weeks. This past week it has not been open at all and I cannot reach anyone connected to the shop. They did not put the pto port cover back on and I can see into the bell housing and I can at least see that there is a new clutch kit installed. My question is; If everything has been installed correctly within the bellhousing and no new slave cylinder is required. If the clutch master cylinder has also been replaced, why can't proper pedal action and clutch operation be achieved?
