fixing lift

please don't make use of otis ever,it's the worst company i have ever seen. i stay in a block of flats where there is a otis lift and a lot of old people. the flat has 7 storeys. the lift stays broken and its broken on/off for 5 years now. they fix the lift get in car and 2 days later it's broken again. i think their staff is incompetent to fix lift. they always have excuses but can't fix the lift,they don't worry about the old people and that they stuck and can't go to the shop. it's a disgrace how they work,they not even worth one star but only a minus.
