Dear Khun Baitoey,
for letting me know about this letter and Bill - I pay this monthly bill automatic from my Siam bank account every month so all ok.
Please note that I receive monthly letters from DTAC and Siam Bank; there is no need to open these - they are just statements or promotions.
Can you please put all letters addressed for me on my living room dining table please?
Sawadee Krab,
David
