use a measuring tape and align the left track with a known straight edge - like the garage wall on the left. then use the tape to take a measurement from the back of the track to the other track. do this every few feet all the way to the bottom. fix what needs to be fixed to get all the same. the door sections "float" on its respective roller bearing at each joint. as far as the HOA agency - I think you have a good reason for a lawsuit against the guy that "fixed" it. he ruined the door when he operated it.
