ND Professional Locksmith Used damaged & deffective locks that won't work West Valley City Utah

ND Professional Locksmith changed the door lock & dead bolt locks on our front & back doors. The "technician" used scratched, dented and defective locks, the dead bolt will not engage. When I complained the company sent the same "technician" who came out and told me there was nothing wrong with the dead bolt, and went outside & locked the door to prove to me that I was wrong. After several tries to get the lock to work he realized that he was locked outside and I had to let him in. He then told me that he didn't know how to fix any of the locks and that he would "get back to me" after he called his boss. I called the "company number" which is the personal cell phone of the owner. I explained what had happened and he said that he would "get back to me". so far I am out $200, and I have 4 defective, damages locks.
