Key word here is SHE ENDED IT. U didn't kick her out. Just called to pick her son up early to give his crying a break. If she ended it then according to your contract her deposit is not refundable because she didn't give notice. She is threating and trying to scare you because she wants her money and she has nothing better to do. keep all her email texts and such and DO NOT respond. Stay firm and strong. I would show that email stating she was the one that called and the bribe of the deposit to cas. Keep going strong ur doing great. It will end soon!
