sycing all my calendars with my iphone

I can't get my google calendar and outlook calendar to sync with my Iphone 7 plus calendar; even though it looks like they should be syncing from the Iphone.

And apple tell me that despite me paying over $1000 AUD a little over 1.5 years ago, I am not eligible for apple support. Sad face emoji.

If anyone has any nice and easy suggestions that would be appreciated.
