Poor workmanship by Takelight projects

I am very unhappy with the service from Takelight projects. They installed a staircase in my house to replace one that had been standing for 15 years but theirs couldn’t even last for 2 years before it started falling apart. I have been trying for the past year to get them to come and fix it and I keep getting the run around. They will make an appointment to come and fix it but they don’t show up. I will have to pursure legal recourse because the staircase has deteriorated such that it is a hazard for my family.
