Before making a payment, the User is able to review and confirm the full details of each transaction. All prices displayed on the website are in Vietnamese Dong (VND). The list price, the promotional price (if any), taxes and the total payment amount are displayed transparently on the order confirmation page. ### Applicable payment methods At present, the AVIS website offers the User the following payment methods: **Method 1: Payment via the MoMo e-wallet** 1. The User reviews information about the Service Packages and selects a suitable package. 2. The User provides/verifies the order information (full name, email, phone number). 3. The system displays the order confirmation page for the User to review the information. 4. The User selects the MoMo e-wallet payment method and confirms. The User needs to install the MoMo E-wallet application, link it to a bank and ensure a sufficient balance for the payment. 5. The User completes the payment on the MoMo application/payment gateway and returns to the Website. 6. The system confirms the transaction, activates the Services and sends a confirmation email together with the Order Code. **Method 2: Payment via the VNPay payment gateway** 1. The User reviews information about the Service Packages and selects a suitable package. 2. The User provides/verifies the order information (full name, email, phone number). 3. The system displays the order confirmation page for the User to review the information. 4. The User selects the VNPay gateway payment method and confirms. The User may pay through a banking application (QR Code), a domestic ATM card/Internet Banking, or an international card supported by VNPay. 5. The User completes the payment on the VNPay gateway and returns to the website. 6. The system confirms the transaction, activates the Services and sends a confirmation email together with the Order Code. **Payment fees:** AVIS does not charge any surcharge when the User pays using the methods above. For payments made with an international card, fees may be charged by the card-issuing bank; the User is kindly requested to contact the card-issuing bank to find out about any such fees. ### Payment security 1. Payment transactions are carried out on SSL-encrypted infrastructure and through the payment gateways of licensed partners (MoMo, VNPay). 2. AVIS does not store the User’s payment card information. Card information and transaction authentication are handled by the payment intermediary service provider. 3. The User is responsible for keeping their account, password and OTP codes secure and for not sharing them with third parties. ### Invoices and payment documents After a successful payment, the User receives an Order Code and a confirmation email, which serve as the transaction voucher. A User who requires a value-added tax invoice is kindly requested to provide the invoicing information to AVIS following the instructions on the website or through the support department within the prescribed time limit. ### Handling failed transactions and refunds 1. Where the User is charged but the order is unsuccessful, AVIS coordinates with the payment partner to reconcile and refund the amount to the User’s original payment method. 2. The refund time depends on the processing procedures of the bank/payment intermediary organisation, usually from 07 to 21 working days. 3. Exchange/return and refund in respect of an activated Services are carried out in accordance with the [Exchange and Refund Policy](/guide/terms-and-conditions/service-testing-and-refund-policy.md) and the [General Terms and Conditions](/guide/terms-and-conditions/general-terms-and-conditions.md) of the Website. --- # Agent Instructions This documentation is published with GitBook.
