Class adjustment SMS

The school newsletter service belongs to the business scope of the Group.

I suggest you go to the local business hall to understand these two points:

1. Does the cancellation of the school newsletter service take effect in the current month or in the next month?

2. If the school newsletter service is opened and cancelled repeatedly in the current month, how will the cost be calculated?

In this way, you can also judge whether you have opened this service and whether you are enjoying it.
