Why did a payment go through without requesting my approval again?
A payment may be processed without requiring additional approval because it was set up as an auto-debit or recurring payment. By approving the payment during the initial setup, you authorized future charges to be made automatically in accordance with the agreed amount and schedule.
This is designed to make payments more convenient, so you don’t have to confirm every transaction. You remain in control at all times and can review or cancel the recurring payment with the merchant whenever you choose.
