Dear Sir or Madam,
I hope this email finds you well.
I am writing to express my dissatisfaction with your new service, which self-service by kiosk that I have used it last friday, and this is really terrible because when I tried to scan books that I want to borrow, this machine had showed error on the screen. Then I passed process to payment step, I choosed to pay by Prompay/QR code, then I scaned it, but it was not work as well, I saw menu to refundable, so I had moved to counter and requested them to support, they do not how to handle this issue, and they do not know ho to refund. Finally,I had to pay again, and staff said It is un-refundable.
I highly recommend you to set-up the section to training your staff that how they manage any problem that may happend with machines, including how to cancel and refund money to user to avoiding to double a payment.
Best regards,
Sasitorn
