Dear Sir or Madam,

On 06/23/2015, I received the items ordered according to the receipt # 3333 issued on 06/20/2015, it
was delivered in Brazil and it was collected in the Port of Santos.


However as soon as we received the items, upon inspection, we noticed that a truck had a quality problem.

However, one of the trucks didn´t meet our required quality standards. I am writing to seek a replacement/a repair.
The vehicle came with the following problem(s):
The door is/are badly done, seeming like a mosaic of steel plates badly welded togheter/the door(s) is/are badly finished, with steel plates welding badly done.

if there are more than one problem you can go as the following:
1) The door plates are badly welded togheter.
2) The door(s) do not open and shut properly.


I would like you to repair both of these faults within a week or a refund...

Please respond to my complaint/complete the work in the next 14 days. If you fail to respond/remedy in this time, I will have no option but to consider taking the matter further.

Yours faithfully

A)
This is just a kick-off, but you can comb the internet and see complaint letters to get new ideas and templates.
The writing is a bit of my creation, but I took ideas from here

and other places.

B) Redoing and comments from the natives and experts are welcome. Anything to improve it is welcome, indeed.
