Otis Elevator Company — Otis elevator in my house

On 10th august 2016
My name is ali alsayegh (e mail ([protected]@gmail.com)
Elevator is one year old. the elevator caught fire in the middle of the night filling the house with thick smoke. thanks god no one was heart. otis service came next day and found the ultra drive was burnt beyond repair. such important part should not be damaged in one year.in the end i was asked to pay the price of part which is equivalent to $4300. i paid for the service and the repair started after couple of days the team found that they have to replace some relays which are not found in stock and they have to be shipped. it is now over 6 weeks and the elevator is down. i installed the elevator to serve my disabled son who is now deprived and hassled for the last 6 week.
Now my complaint is
1- why is it taking so long time for the repair
2- why important parts not available in a country so big like saudi arabia
3- why do i have to pay for a part that normally should live the entire life of the elevator. (it is one year old with very light usage and caught fire while the elevator was not used)
