How to Officially complain about your matters

Gather your records

The first essential step before writing this letter is collecting all your documents regarding the issue you want to complain about. It will help you craft and organize your idea to compose a good note. After that, attach all the proof you have with the letter, such as sales invoices, contracts, valid warranties, or photos of product damage.

Find out and Contact the Sellers or employer

You may need to know who will be responsible for solving a complaint in your company in order to address the matter to the correct receiver; it could be your boss or higher authorities. Once you find out to whom you should send this letter, it is recommended to set up a meeting to talk in person first so that they can know the overview of the matter before receiving your letter of complaint attached with records.

You can call the retailers or manufacturers' customer support regarding products and services. Still, we do not recommend it because calling customer support recently is annoying, and you must first find the correct phone number. Then, you will wait and listen to a long automated system to direct you to the correct department where you can speak about your matter. Indeed, It would be a fantastic way to express your problem if you not be stuck too long waiting on hold to talk to a particular person in charge.

Instead, you can send this letter first to notify them through their customer services website or their contact information by email. Nowadays, most companies will have a bot chat or online chat to contact directly on their website and tell them to check the email you sent to provide a solution. Doing this will save you energy and time in waiting on hold for so long.

Seek legal help

Despite sending a complaint letter, you haven't received any positive outcome to solve this matter. Then it is your time to consult with a licensed lawyer or seek help from 🔗a consumer organization or local Government. This link will provide contact instructions to go through the legal system from the Government and find low-cost legal services.


You can attach the copy to send by email or post mail, but do not lose your original paper as it is a crucial record for the case.


Writing a complaint letter needs to explain the reason with eligible evidence precisely. Though this matter does not happen often, you will encounter a situation in which you need to send a complaint letter to help the receiver improve their services/products and compensate for what it damages to you.
