Dear Mr. Brown,
The reason I am writing this complain letter is that I think the buildings security service is not sufficient enough.
First of all, elevators despite the constant care, I want to mention the almost intact. When I saw that measures still was in shock. Administrators are not related to this topic. Most people is safety is at stake.
I think you would be interested with this problem. I hope can show the necessary importance to your elevators.
In a good complaint letter, the first sentence should say what you want done.
I am sorry to say that your letter is hard to understand. I understand that the elevators are unsafe, but I don't understand what the problem is. If it is a problem that can be photographed, if I were you I would take a picture and enclose it in the letter.
Bir cok Grammer ve kelime hatasi var. Cogullarda yanlis kullanilmis.
