What is the issue you’re encountering

It’s not only upgrade or downgrade issue of the plan. It’s including not being cancelled or being incorrectly billed and It’s seems to be a serious issue, but I don’t know why you guys are so complacent. I think this will be direct to reputation. You should handle tickets and refunds immediately and also consider compensation for the wrong invoices.
