Why is Mitali treated like a servant?

Why nothing is posted here.? But going by the heading, Mithali already lost her mother and father is now termed as thief, she is in a awkward position. But I don't think anybody treats her like a servant. Doing a little housework is not being servant. Dadi who used to taunt her a lot is also mellowed down now. Otherwise Rishab, Raina, Naina all love her where as Yug, Mohini, Nalin stay neutral.
