Building violation court hearing

[Addy Anders]

I own a single family home in the city of Chicago. I received a violation in April and have a court hearing in June. This is my first property ever. The contractor who built my fence scammed me. I cannot get a hold of him and he isn’t easy to work with anyways. I do not know what to do or who to contact. Every time I contact the city of Chicago building department, they never answer. Does anyone have any recommendations?
