According to your international call fee claim received last month,
I found that you have called to Mr.Sato/INB’s sale on 8 Jun 2016.
The rate was 22THB/min.
As you may know or I’ve told and beg you to call beginning with ‘00500’ or ‘003’ or
any code to make the phone call charge cheaper (6or7THB/min).
But, your claim form still shown the expensive rate!
For this time, I would just notice you via this mail and,
hope you will take more concern when you call aboard.
Your understanding and cooperating would be highly appreciated.
