My children daycare made me sign a contract upon enrolling. The contract stated that I must give a two weeks notice before unenrollment. My agreed upon due date to pay the tuition is the 10th of each month. I submitted my two weeks notice today 8/23/2013 which makes 9/6/2013 my last day. She is telling me that I will owe her a week and a half of tuition, which I find hard to believe since I have no outstanding balances. Is this a breach of contract since I gave my notice two weeks in advance?
