We recommend you to buy tickets based on your driving habits, and do not purchase tickets that you are unlikely to use. However, if code tickets have been purchased but cannot be used within 3 months of purchase, go to one of the customer service centers and submit a refund application, indicating the customer’s identification code and / or mobile phone number, as well as the bank account number, if you want to receive a refund by bank transfer. Payment for tickets can be received in the amount of 90% of the specified amount.
