Issues with payments
1. Contact has not received the payment: If the payment is complete, but your contact has not received the money, check that you have sent the payment to the correct contact.
2. Payment was not completed and refund was not received: If a payment was not completed, the app will notify you. The bank should process a refund in up to 4 business days. You are advised to check your bank account to know the status. In some cases, you may need to contact support from within the app. To contact support, tap the payment message > Help.
3. Unable to add bank account: If you are not able to find your bank in the list, make sure your bank supports UPI. If you are having issues adding your bank account, check your WhatsApp number and the phone number linked to your bank account is the same. If not, contact your bank.
4. Unable to send payment: You will not be able to send money if your contact does not have payments enabled. You will see the following pop-up message when trying to send them money: To receive a payment, [contact name] needs to set up payments in WhatsApp by tapping Settings > Payments.
