I suggest rescheduling the class
I am sorry to hear that we have to cancel the class again. We have't had much luck.
If it is possible for you, I suggest resheduling the class this week. The best time to make up the class is at 18:30 Sunday (your time). If you are not available this week, we can make up the class at 18:30 from Monday to Wednesday next week. Let me know.
