What a good complaint letter says
Short, factual and polite wins. Write it as if a stranger who knows nothing will read it later — because a mediator, the DTI or a judge might.
- What happened, with dates, places and names.
- What you already did about it (calls, chats, visits).
- Exactly what you want done, and by when.
- How to reach you, and copies of your proof attached.
What to leave out
Insults, threats and posts naming the other side online. They weaken your complaint and can expose you to a libel or cyber-libel case. Keep it to the facts.
Questions people ask
What if the company ignores my letter?
Keep your proof of receipt. For goods and most services, you may then file a consumer complaint with the DTI. Utilities, banks, telcos and insurers have their own regulators (ERC, BSP, NTC, Insurance Commission), and each takes complaints.
Should I send the letter or hand it over?
Either, as long as you can prove it was received. Hand it over and have the person sign and date your copy, or send it by registered mail or courier and keep the receipt. An email copy helps, but a signed receiving copy is stronger.
How long should I give them to answer?
Five to fifteen days is usual. Long enough to be fair, short enough to show you mean it. Write the deadline as a number of days from receipt.
Is this legal advice?
No. It is a common Philippine format for a written complaint. For a serious injury, a large amount or a criminal matter, talk to a lawyer or the Public Attorney's Office (PAO).
