With reference to the courts meeting, I recall that it was best for you to make an appointment with Khun Fah and jointly review and agree the status of the utility bills to date. The records dating back for over a year are far too big to be issued again via email and Khun Fah has all of the required information readily available at her office.
For the future invoices, you are required to make an appointment to witness the various meter readings jointly with Khun Fah.
