In India, we have a direct (bank to bank) payment system known as the Unified Payment Interface (UPI). UPI also offers an auto-pay e-mandate feature. Once set up for a subscription, if the subscription is canceled, payments will still be deducted from your bank account. You must manually cancel the e-mandate after cancelling the subscription through the merchant app. Any deducted amount is automatically refunded within 7 days.
It's advisable to cancel the e-mandate through the payment app before the due date to avoid charges and ensure automatic cancellation of subscriptions on the due date.

Please note: The process for canceling a UPI mandate may vary depending on your bank or service provider. For precise instructions tailored to your bank or service provider, please refer to their respective services.
