I am the contractor can another one be hired without first telling me
I am the contractor. I was to build a inside wall. After job was done, later customer was not happy. Without informing me, hired another contractor to work on wall because they were not happy with work. And because they were unhappy with my work, they want me to pay the new contractor for work that has been done on wall because they say it was my fault. Can they make me and by law were they suppose to inform me first before they hired other contractor.
