I do not know how condo associations work, but if you did not put the wires there, it would seem that management would have some manner of responsibility, so I would contact them first. If they are not responsive, or if it is determined that it is not their responsibility, i.e. you bought it "as is", then you need to contact an electrician. Regardless, you should act on this immediately, to ensure that nobody is injured, or worse, and that whatever work that is not right is made right. You do not need to contact your utility company.
