When i received the inquiry from customer, i reply it with 24 hours, it means the free entry point conversation is opened? After that, i sent the marketing template message within 24 hours, but i found it charged marketing template fee(please see the pic), in the price document, it shows"Once the free entry point conversation is opened, you can send any type of message to the customer without incurring additional charges.", have i confused any explanation? please help, thanks
