My stepsister no longer keeps calling my mom for money and somehow has found out her unlisted number. What do I do. Do I change my moms number or get a restraining order so she cant call. I think I have her email address. Do I maybe email her and tell her to stop calling my mom for money. Her father has been dead for 31/2 years. Three years ago my mom gave her money that was her dads and she spent it all. Now they want more. My mom doesn't have it anymore.
