Dear K.Chanicha,
I would like to thank you for giving me the opportunity to have an interview. As much as I want to meet you on the appointed date, I afraid that I may unable to go to meet you on time because of I have a urgent conference meeting with KL and Indo team on Friday, 1.00-3.00 PM.
I am asking for your kind consideration to move the interview on the difference date. I suggest on today (Thursday, 17 July) evening time. Please let me know if you can re-schedule on this date.
I hope for your positive response. I am sorry for postponing the interview and I`m thanking you again for the opportunity.
