怎樣用英文寫出～拒絕公司提出進升的建議?

"進升"是神?

I am writing to ask for your reconsideration of my recent promotion to CEO of the Global Sales Group.
My current position of Head Janitor of southern US has been challenging, though satisfactory to my career plan so I would like to stay on this position for another decade or so.

Thanks for your recognition

Dear Sir,
---In reply to your asking me to be promoted to (---) position, I am honored but unwilling to accept the offer as all opponents do not show their consent to permitt me, to your disadvantage..It might be proved wrong in your haphazard opinion or ordering, whether admitted or not.
----I shall discuss with you further of my future promotion ,as you suggest,planned,and considered.
--------------------------------Yours respectfully,
-------------------------------------Chris Wang,

In view of that, I have to ask you to reconsider my case. Thank you very much. Yours faithfully So and so signed date:-------. Yip
