Subject: Warning for site contractor on using poor material

Dear Rick Dick,

Please be intimated that few months ago, you had signed the letter of agreement that said following things:

1-  The plot sized 1 kanal must be constructed as grey structured model.
2- The construction period must not exceed longer than four months.
3- A grade brick must be used in the building material.
4- Concrete and lantern material must be of excellent quality that will be used in the construction of the house.
5- In case, any of the above mentioned clauses ignored or found alternate to it and without intimation and consent of the owner, then the site contractor is liable to pay the fine for using poor material whether in concrete or bricks together with returning the poor material used in construction of the building.

I was routinely on survey to see the progress of the work and to my
surprise, the bricks I saw at the back side of the portico were of low
quality but the price was taken from me on the basis of A grade brick. I was not expecting this cheat even after the clearest words as written in the treaty. I demand the last clause of the agreement to be fulfilled by you or otherwise I will freeze your remaining amount. I hope you understand what I say.
