Dear Khun Chotiros
Good day to you.
I really need your advice on the above GOP that has been long outstanding.
We seek your kind help to check with the provider if there is outstanding bill for this patient. We need provider to send us the invoice soonest for this GOP as it’s been outstanding since last year May 2013.
Alternatively, please advise if GOP can be closed.
Thank you and await youradvice.
Warmest regards
Nan
