Dear Khun Taechinee,
This is not the first time that you requested the BG and need it immediately without giving us time for preparing it.
Please clarify why you just requested BG on 23 Dec’15 even you got the information since 16 Dec’15.
This is not normal process and you must send direct email to my team and call to clarify more detail.
I believe that you aware the normal processing time of bank to get the BG is 7 days and if you request backdate in BG bank need 14 days.
In this case I will do my best by request BG date 25th Dec’15 for you before 3 P.M., please contract Khun Kanteraya.
I hope we will win the bid.
