You might want to reboot your phone and see if that helps.

@SekyoungWon , did you include a plan change with the scheduled renewal?  If so, a glitch in the system is the most probable cause.  You will need to use the chatbot link at the bottom of the webpage to initiate a support ticket and have a CSA rectify the problem.
