How to write a letter to neglect the post nominated by council

Dear Sir,

I am grateful for the honor and courtesy of being nominated for membership in the council.

I am sorry I am unable to accept, as I am leaving for abroad at the end of this week. I will probably be left for a year or more.

Please convey my sincere thanks to the nominating committee. I hope I shall again be given the opportunity to join on my return from states.

Sincerely Yours,

How to write a letter to the postmaster about the non-delivery of a gift parcel

To the postmaster about the non-delivery of a gift parcel :

Dear Sir,

My sister Diana has sent me a birthday gift from New york 10 days ago. Till date, the parcel has not reached me. The bill number is PO No.555. It seems, the parcel is delivered to somebody else or it is lost in transportation. I request you to kindly look into the matter and ensure early delivery of the parcel.

Yours faithfully,

(your name)
