Dear Mr Kelly
Thank you very much for offering me the position of Customer Service Manager

While I understand the position and your company offer a great deal to a

matches what I am looking for. Therefore, after giving it much careful thought, I
must decline your offer.
Thank you for your time and effort. I wish you and your company well.

Dear Mr Heron
Thank you again for offering me the opportunity to work at XYZ Company.
As I told you over the phone I regret that I must decline the job offer. After
considerable thought I have determined that the position is not the best fit for me
