I scheduled a lesson, allocated time for it, and postponed all other engagements. I was eagerly waiting for the lesson. However, just half an hour before the scheduled time, the teacher informed me through the chat that they would not be able to conduct the lesson. It's horrible!!! I'm new here, but this kind of attitude from teachers is not encouraging.
Do cancellations like this happen often? Are there any consequences or punishments for the teachers?
