Sometimes you acquire the services or products of some company and it does not live up to your expectations. You want to register your complaint and get compensation but lack of knowledge comes in your way. If you are unfamiliar with the procedure then let me tell you that a complaint letter is your best bet in such conditions.
An effective complaint letter can resolve your problem and get you the compensation which you did not even think. Remember, writing a short and snappy complaint letter is a tricky job but you can file your case effectively with this technique.
In first paragraph of your letter, provide your addressee the complete information of your purchased product/ service. Give exact date, location and other important details.
Use second paragraph to give reason of your complaint and then request proper investigation to resolve the issue.
In the next paragraph, remind the other party to check the attached documents / evidence and your contact information. Then close your letter with some courteous salutation.
