We never were confidant as to WHEN the technician was going to show up, when he did show up he had the work skills of a gorilla. He was admittedly over extended and overbooked.. when present he tore packing/boxes open and strew materials about in the kitchen.. At one point he dumped a can full of screws, bolts an d washers directly onto our newly finished wood floor.. when actually working he did seem to know how to make the repairs.
