Great about taking care of the elevator and its controls.
The apartment building in Denver where I live has Kone elevators. They are the worst, most unreliable elevator systems I have ever seen. They are out of order at least once a week and when they are working, they are extremely unresponsive, slow and have a mind of their own.
Great service, dont listen to the other guy. Its a good company.
Inadequate customer Service, As well as lack of competency in elevator maintenance and servicing from technician.
