if this guy was going to have your stuff installed he would of had it done right then and there when you first got there, for the equipment you got it wouldn't take more than 2-4 hours to be done, he's giving you the runaround and obviously has no regards for your friends debt, tell him to f>ck off and tell your friend to confront him over the money, I can't believe how unproffessional this prick is being, BTW it shouldn't cost much to have the stuff installed, couple hundred or so, take your van somewhere else and pay what you got to pay to get it done and over with
