I am sss. You interviewed me about one month ago for the position of sss in sss.

I would like to sincerely thank you for offering me the position and, although at the time I turned it down, I am now very interested in taking up your offer. If the position is still open, would you please give me this chance again? I am confident that I’m qualified and prepared for all the challenges of this position.

Thank you for your time and consideration.

You might want to explain why you turned it down and why you have changed your mind. If they think you are just fickle it will put them off giving you the job. You need a very good reason for not taking it (one that won't make them feel criticised) and an equally good reason for now changing your mind (so it doesn't sound as though you are now settling for this even though you still don't really want the job).
it was very king of you. ok i will revise them. thanks
