Mrs. W calls your office and speaks to your legal assistant about a possible Human Rights Code complaint. Your legal assistant takes down Mrs. W's name, telephone number, address, and some details about the matter, including information about some of the incidents that have led Mrs. W to believe that she may have grounds for a complaint. Your firm has no record of Mrs. W in its conflict checking system. You call Mrs. W and leave a message on her voice mail, asking her to return your call. She does not return your call, and you never hear from her again.
