MBP Heating and Air INC- Put holes through ceiling during water-heater install Richardson Texas

During a water-heater installation in my attic, in-which MBP heating and Air inc. forgot to pull a permit for, the "repair man" put his leg through the second floor ceiling.  The damage was caused after an inspector finally showed up and told the installer that he had hooked the gas-line up incorrectly.  Jeff, I believe he is the owner, has been rude, doesnt return calls, and has flat out told me that I am delusional for wanting the ceiling fixed and that he should sue me for his mans foot going through the ceiling.  Totally unprofessional and uncaring for the damage and 3rd-rate work his team performed.
