Rearview System Braking problems of the 2020 Ford Mustang

Went to clay cooley Ford in arlington TX off of highway 360 to have rearview camera issues fixed after being sent a recall notice to take it in to be repaired. The vehicle doesn’t show a black screen all of the time but it is at times distorted or black. Upon arriving my husband was told that one they don’t have the camera for the vehicle mind you an appointment was made I didn’t just show up and two because at this present moment the screen wasn’t showing distorted or black screen they were not able to repair the recall we were given a paper to contact a man who works at the dealership the vehicle camera wasn’t thoroughly inspected, just asked if it was doing it now when my husband said not right now but it does show a black or distorted screen sometimes he was sent on his way and told the repair couldn’t be done. I have reached out to Ford customer service to get their help with getting this recall resolved because I do transport a child in this car daily to and from school.
