Maintenance for the week of November 4:
• [COMPLETE] ESO Store and Account System for maintenance – November 6, 9:00AM EST (14:00 UTC) - 6:00PM EST (23:00 UTC)
My ESO+ is via Steam and I always cancel immediately after I renew, because I prefer not to auto-renew. This means I'm pretty much permanently active but cancelled.
As of today the time my ESO+ ends has gone back by one month, and it has remained in the cancelled state, and my account has been credited one month worth of crowns.
