We paid for the expert installation and the person that was sent did a good job up to a point.  He arrived at 6pm and at 8pm he told me that he only was booked for a two-hour window.  He was not finished putting everything together by the time he left so there is still one item left in the box.  When you pay to have something assembled one would assume that the entire set would be assumed.  Not just the pieces that can be put together in two hours.
