Busy Schindler Service Lift at Sunway Resort Hotel, New lift Mitsubishi & read discerption

This Lift is very busy because there is an event going on 1 lift is working the chefs, staff and cleaner are using it so it is so busy as hell even no chance to show the other side when it is on 15A and 15 only sorry because there is too much worker. When i was recording quietly the Cleaner ask me may question so i have to answer them i had no choice. They told me some information about the lift, doors close does not work it is bad they said it was like that also have to wait even press the button is no use. This lift actually has 2 side one front and one is rear, the chime is working well even the lanterns inside the lift the indicator on the rear side is not working but the front side is these schindler are very classic on 9F is very special the new Mitsubishi Lift has and lantern and indicator that's good and i think LF also will have for other floors still no indicator only lanterns weird? any questions pls comment down bellow
