Hi HelpMeNowPlease01,
Thanks for contacting Apple Support Communities!
We understand that you need some help to remove a spam calendar invite.
Check out this resource which will show you how to remove a spam calendar invite: Delete spam calendars and events on iPhone - Apple Support
"How to remove calendar spam on your iPhone in earlier versions of iOS
- Open the Calendar app.
- At the bottom of the screen, tap Calendars.
- Look for a calendar that you don't recognize. Tap the More Info button
next to that calendar, then scroll down and tap Delete Calendar.
If this doesn't fix the issue, delete the calendar subscription in Settings:
- Open the Settings app.
- Tap Calendar > Accounts. Or if you use iOS 13, tap Passwords & Accounts > Accounts instead.
- Tap Subscribed Calendars.
- Look for a calendar that you don't recognize. Tap it, then tap Delete Account."
We hope this helps you.
Cheers!
