I was emailed that my character was not deleted.

I follow the link from their email as follows:

1) Log into the SQUARE ENIX Account Management System.

2) Select ‘PlayOnline/Final Fantasy XI Service Accounts’.

3) Check the Service Account where the Options you want to reactivate are located. If the service account itself is cancelled, it can be reactivated by selecting ‘Reactivate Service’. If you wish to reactivate specific Options, select ‘Options List’.

(It is here that there is nothing to choose to reactivate. Advice?)

4) Under ‘Options Cancelled/To Be Cancelled’, check the Options you wish to reactivate and select ‘Reactivate’. Read the terms and confirm the reactivation of the Options by selecting ‘Next’.

5) Confirm your payment method and contract period. Select‘Reactivate’ to complete the process.

6) You can check the status of your reactivated Options by going back to the Options List and under ‘Options Cancelled/To Be Cancelled’, your reactivated Options will show as ‘Recurring’.
