The payee has informed us that the money order has not been delivered until yesterday.

We, therefore, request you to please personally consider the matter and do the needful by returning the post.

Yours faithfully,

#3: Complaint Regarding Water Charges


The Zonal Assistant Commissioner,
Municipal Corporation,
Flint, Michigan.


Humble apologies to inform you that I have not yet got Water Meter fitted at my house although the asked deposit was already made about eleven months back. With the fact that I have no water meter at my home, I am being billed USD 35.95 each month.

Worse of all is the summer months when we do not get sufficient water for drinking and taking a bath and yet we have to pay the same amount each month.

Time and again I have approached your subordinates requesting them for arranging a water meter but always lame excuses have been given.

I know for certain that because of an acute shortage of water in Flint, it may not be possible to increase the supply of water in our locality but you can certainly arrange water to relieve me of the burden of extra payment I am being asked to make.

Please note further, in case no meter is arranged within a month, I shall not only stop making payments to your bills from next month but shall also take legal action at your risk and cost.

Thank You.

Yours Faithfully,
Brandon Brine

Kindly refer to your notice No. _______ dated ___/___/______ communicating the proposed exorbitant rateable value arbitrarily fixed by you in respect of the above premises for the year ____-____ and my objections, therefore, are appended as under:

  1. That the proposed unjust discriminating and irrational rateable value fixed on the hypothetical basis is against the letter and spirit of Section ____ of the Municipal Corporation Act and is not acceptable to me.
  2. That the proposed enhancement in the rateable value from USD _____ to USD ______ now proposed for the period _____-______ without any cogent reasons which have not been communicated to me is unwarranted.

  4. That the rent fixed by the Government for these premises is USD ______ and as such its rental value cannot be increased as provided in the provision to Section ____ of the Municipal Corporation Act.
  5. That the said premises are occupied as before

In view of the above facts and circumstances, it is required that the notice under reference may very kindly be withdrawn and treated as canceled and I may be charged the same amount as was assessed in the previous year although that amount too was more than what it should have been.

Yours Faithfully,
Caleb Samuel,

#7: Complaint About a Cinema


Deputy Commissioner,

Dear Sir,

We the undersigned inhabitants of XYZ Society bring it to your kind notice that “ABC Cinema” located in our society, is a cause of irritation and annoyance to all the inhabitants of the society.

The situation becomes worse at night when the last show is over. People come out singing vulgar songs and using similar language. Not only sleep is disturbed but also the atmosphere, especially for the female sex, is spoiled.

As you are aware the inhabitants of the colony come from the middle class, and it is necessary to have complete rest at night.

We have already pointed out this difficulty in our previous three letters but regret to say that no action has been taken by you so far. We, therefore, request you once again to please instruct the Cinema authorities to change the existing gates of the Cinema to the eastern side.

Please note, if no action is taken within one month from the date of this letter, we shall be obliged to take legal action at your risk and cost.

Yours Faithfully,
