SE deducted more Crysta than it should

Thank you. That's the case in fact.

As for the "5 additional retainers", is there any option for "0 additional retainers"? I can't see one. The minimum is 1.

Mogstation > Your Account > Retainer Service > Cancel Subscription

It'll have you confirm that you wish to disable the renewal of your extra retainers at that point. After the remaining time you've paid for is up the additional retainers should no longer be accessible. If you use them, make sure to take any items/gil off them before the time runs out. They could probably name that particular button something better like "Cancel Retainer Services", but that's what it's for under the Retainer Service category.

It's not using the additional retainer service.
