Dear sir,
As you make an interview appointment on 5th October 2015, Thank you very much for considering carefully my application.
But unfortunately I have recently signed agreements to work with other companies already.
However, I would like to thank you for review my qualification and experience to assess my suitability with you.
Hopefully we can work together as possible ,if I have a chance.
Best Regards
Prempratya Premvijit.
