Now I cannot get the clutch to disengage

(as a side note, all work has been done by my friend not me)
I recently had to replace my 5 speed manual transmission. Now I cannot get the clutch to disengage. At first we Had issues bleeding the clutch. Even tried to burp the line to get any excess air out. We finally got good compression. The slave has also been replaced during of this. (Both master and slave were replaced less than 2 years ago) at this time we are at a standstill trying to figure out what to do next. He is a tow truck driver and doesnt get much time to work on it. Everything I've researched points to the TO or master and slave again. Please help! Been without my truck since first week of August! Desperately wanting to get her back on the road.
