12Go Train Tickets Not Received – Request Booking Update

I bought train tickets on the 12go platform for the Hakata Fukuoka–Hiroshima route, but to date I have not received the tickets or any explanation about the status of my purchase. In the receipt issued in the name of Arturo Julio Zegarra Zuniga, the amount charged is 105.34 SGD for this journey, so the payment was processed correctly but the service has not been provided. I kindly request that 12go inform me clearly and without further delay about my booking and immediately send me the train tickets I purchased, or otherwise provide a prompt and appropriate solution.
