Hi , we had an appointment at KARMA SALONS on 4/13 at {time} . And I received a message that told me " Hi Todd , KARMA SALONS has rescheduled your appointment to 4/13 at {time} CDT . " I thought it was ok . 4/13 is Saturday so Todd does n't go to school . But I just notice Todd will go to his classmate 's birthday party at {time} . So we need to cancel the appointment . Thank you .
