Legal notice for a consumer complaint: format and what to include

In short

A legal notice is not compulsory before a consumer complaint, but it often settles the matter, and it becomes evidence if it does not. It should identify the purchase, describe what went wrong, say what you want and give a reasonable deadline, usually 15 days.

Is a notice required?

The Consumer Protection Act, 2019 does not require a legal notice before filing a complaint. Sending one is still good practice. It gives the seller or service provider a fair chance to put things right, many disputes end there, and the notice and any reply show the Commission that you acted reasonably.

What to include

The full legal name and address of each party you are writing to: the seller, the manufacturer, the service provider or the platform
What you bought or hired, when, for how much, and the invoice, order or policy number
What went wrong, with dates, in plain words
The complaints you have already made, with reference numbers and the responses
Why this is a defect in goods, a deficiency in service or an unfair trade practice
Exactly what you want: repair, replacement, refund, compensation, or a specific sum
A deadline, usually 15 days from receipt
That you will file a complaint before the Consumer Commission if they do not comply

Mistakes to avoid

Writing to the wrong company. Check the name on the invoice or agreement.
Claiming amounts you cannot justify. Keep the demand reasonable and explain it.
Threats or abusive language. They weaken your position.
Waiting too long for a reply. The two-year time limit keeps running.

You can send the notice yourself or through an advocate. Either way, the notice is valid.
