How to Write a Strong Letter of Complaint

A well-written complaint turns a frustrating experience into a clear request that another person can act on. Instead of describing every irritation, a letter of complaint identifies what happened, explains why it matters, and states the outcome you want. This is particularly useful when an informal phone call has not solved the problem or when the business needs a written record.

A strong complaint is factual, concise and courteous. It does not need dramatic language, exaggerated claims or a long argument about how inconvenient the problem has been. Its strength comes from accurate dates, supporting evidence and a reasonable request for a refund, replacement, repair, correction or other form of redress.

Australian consumers can also rely on protections beyond a company’s goodwill. The Australian Consumer Law covers many purchases of goods and services, while different rules apply to vehicles, financial products, telecommunications and some other industries. Knowing which area applies helps a complaint remain focused.

Begin with the problem and remedy

Start by deciding what the complaint is asking the business to do. “I want someone to fix this” is too vague. A useful request might be a refund of $189, a replacement product, a free repair, correction of an incorrect bill or written confirmation that an account error has been removed. A specific request gives the recipient something concrete to consider.

Next, identify the facts that make the problem serious. Include the product or service, purchase date, price, order or invoice number, location and a short account of what went wrong. If an item arrived damaged in Melbourne, for example, record the delivery date, visible damage and whether you accepted it. If broadband service is unreliable in Brisbane, note when outages occurred, their duration and the tests you have already completed.

Separate a legal entitlement from a change-of-mind request. A faulty product or poor service may fall within the Australian Consumer Law, but wanting to return an unused item merely because you found a better price is different. Unsatisfactory quality, lack of care or skill, and goods that differ from their description can create stronger grounds for a remedy than simply disliking a purchase.

Gather evidence and choose the right recipient

Keep every relevant receipt, invoice, warranty, order confirmation, email and photograph before writing. Take screenshots of error messages, account balances, tracking information and dates on which technicians attended. A timeline is especially helpful: list what happened, who you spoke to, what advice you received and what action was promised. These details allow someone reviewing the complaint months later to understand it without relying on memory.

Send the complaint to the organisation with the authority to resolve it. This may be the retailer, service provider, manufacturer or another named entity on the receipt. Australian businesses such as Woolworths, Coles, JB Hi-Fi and Officeworks may have different processes for online purchases, faulty products, refunds and customer feedback. Read the contact page carefully and address the message to a complaints or customer-care team rather than sending it through a general enquiry form.

Use Australian dates, amounts and addresses so there is no ambiguity. Write dates as “4 August” or “04/08” rather than “8/4”, which can be misunderstood. State prices in Australian dollars and identify each attachment clearly, such as “Invoice 58291” or “Photo of damaged appliance”. Keep the originals and send copies unless the organisation specifically asks to collect something.

Build a clear, calm letter

A specific subject line helps the complaint reach the right desk. Use a format such as “Refund request for faulty blender, order 58291” or “Complaint about incorrect electricity bill, account 19452”. Avoid emotional subjects such as “Appalling service” or “This is unacceptable”. The subject should summarise the issue rather than blame or criticise.

The opening should identify yourself and the transaction briefly. Mention the business, the date and the amount, then move directly to the problem. For example: “I purchased a $249 blender from your Brisbane store on 4 August and collected it on 6 August. It stopped heating during its first use, and the product no longer operates as described.” This gives the reader the essential context without an extended retelling.

Organise the body in a logical order: what you bought, what went wrong, what you have already done and what you now want. Avoid personal attacks against an employee, even if a staff member handled the original issue poorly. Complain about the action or failure to act rather than labelling someone incompetent or dishonest. Courteous language also makes it easier for a complaint handler to remain objective and move the matter forward.

Close with a clear request, a reasonable response date and your contact details. “Please confirm by 23 August whether a refund will be issued” is more useful than expecting the reader to infer an action from a long complaint. Use a professional closing such as “Yours sincerely” and retain a copy of everything sent.

Make the requested outcome specific

The remedy should match the problem and the circumstances. Where goods are not of reasonably acceptable quality, the Australian Consumer Law may provide options such as a refund, replacement or damages, depending on whether the consumer has rejected or accepted the goods and what the law permits. For services, the issue may be whether due care and skill were used. A repair request is reasonable when the defect can be fixed, while repeated failed repairs may justify asking for a refund.

State why your chosen remedy is appropriate. For instance: “Because the appliance has failed after three attempted repairs, I am requesting a refund of the purchase price rather than another replacement.” This explanation shows that the request is serious and proportionate. It also discourages an automatic or misleading response that merely repeats a standard policy.

A compact complaint might read: “I bought a television from [business] in Adelaide on 10 July for $1,200. It developed a permanent vertical line during the first week. I contacted customer service on 11 July and again on 18 July, supplying photographs and the installation record. The promised replacement has not arrived, and the television is still unusable. I request a refund of $1,200 because a further replacement would leave me in the same position.”

Add the purchase date, reference numbers and a response deadline, then adapt the wording to the facts. Do not cite legislation unless doing so helps explain the request. A sentence such as “I believe the television is not of reasonably acceptable quality under the Australian Consumer Law” may be useful, but accurate facts remain more important than legal language.

Escalate without losing control

If the business does not respond, send a short follow-up rather than repeating the entire complaint. Identify the original message and date, summarise the unresolved issue and repeat the requested remedy. Ask for a reference number and a response by a reasonable deadline. This creates a clear record of how often you attempted to resolve the matter.

Keep a complete file after that. A useful final escalation includes a one-page chronology, copies of the original complaint, every response, relevant evidence and a short statement of what remains outstanding. Send the material through the organisation’s formal complaints process and ask for review by a manager or complaints officer. Avoid making threats in the first letter unless escalation is genuinely the next step.

External bodies differ in what they handle. State or territory consumer affairs offices can assist with many consumer and fair-trading disputes, although vehicles purchased through a dealer are generally covered by state and territory fair-trading laws rather than the Australian Consumer Law directly. The Australian Communications and Media Authority handles telecommunications disputes in some circumstances, while AFCA deals with eligible financial complaints. The ACCC generally enforces consumer law and monitors business conduct rather than resolving every individual dispute. Privacy complaints may need to go to the Office of the Australian Information Commissioner.

A strong complaint leaves behind a calm, evidence-based account and a specific request for correction. Its purpose is not merely to express annoyance, but to identify the harm, show why the requested remedy is justified and give the organisation a fair opportunity to put it right.
