Click on the harassment information of iphone calendar, and what should I do if I refuse?

Find the settings you want to delete from my iPhone.

Now that you have clicked the Reject button, the remedy now is to go to Settings-Email, Address Book, Calendar-to the bottom-and close the events found in the email. Then open the settings-find iCloud- turn off the synchronization of the calendar-delete it from my iPhone, and you can empty the calendar spam reminder at one time, including your own settings.
