Lacks customer service and business ethics.
I called to set up an appointment and it took several days for a call back. He was unable to give me an appointment, but maybe next week. He would have to call me back. Then he asked me for my number, as he does not have it. (Did he not just call me?) Anyway, the attitude of the conversation was that he didn't want anymore work or he just didn't care. And you guessed it, he never called back!
