Otis Elevator Company — Non-stoppage of lift car in required floor

Self a resident of eight - storeyed building at new town kolkata-156, having a duplex lift of your concern facing enormous problem using the lift.
A. While one person from topper floor press button, the lift car cannot stop anywhere in between though another person press button for upward/downward use, but another lift car (If in rest) attend the 2nd person.
My query is what technology it adapted? Is it higher technology or degraded technology?
I think it violates the ethics of lift facility.
Totally misuse of power and valuable time.
It should be revised to get free access in our premises.
