Unprofessional, Unreliable maintenance man

I hired this individual, who advertises his business on the Northcliff community page, to do some minor maintenance works around my apartment. It entailed fixing taps, plugs, replacing a window, sealing around basins, adding shelves in wardrobes and replacing 1 kitchen unit. He started the works on April 2nd. Didn't finish and came back the following Monday, only after having had harsh words with him, as he tried to get out of finishing on this day. Still he didn't finish the work. Came back that Friday afternoon and again Saturday morning with more excuses of why he couldn't finish the job. Since then, he has been avoiding my calls. I have paid this man in full for a job he has yet to finish. The small things he have done, is of poor quality and I will have to get someone to redo it. Furthermore I'm stuck with an unfinished kitchen unit. What an amateur and a conman!
