After the end of the rental relationship, my tenant moved out, abandoning his property in the premises that he rented. After some time, it turned out that the air conditioner installed in the ceiling with all its components belongs to the bank. The bank demanded the air conditioner back. But air conditioning can only be removed by breaking the ceiling. The bank refuses to compensate me for the cost of repairing the ceiling and requires air conditioning. What should I do in this case?
