Electric (pa)

So our breaker box has been tripping and we have found out that it's tripping because we have 70% of the first floor wired to the same breaker. We've had people out to look at it who have told us the cause what what can most likely fix it and that's breaking the 3 rooms on to 3 separate breakers. Since we've learned this we've made contact with our landlord and the contact incharge of our property and the only thing that's come up is our contact has changed. Anyone have thoughts or ideas on what we can do? We have only been here coming up on 4 months at this point.
