Pausing, rescheduling and extending are proposals: you raise one and the other side agrees. A schedule one person can change alone is not a schedule.
Ending a tuition is not a proposal. Either side can do it, with a reason, without permission. Where the refund rules say something is owed on the media fee, the refund is raised for you at the same moment — you do not have to ask for it separately.
A guardian can also ask for a replacement tutor. That reopens the original job with its history intact, rather than making you start again.
Still stuck? Open a support ticket and a person will answer.
