A service is deficient when its quality, nature or manner of performance falls short of what the law requires or what the provider itself undertook to do — not merely when you are unhappy with it. Section 2(11) of the Consumer Protection Act 2019 defines the deficiency, and the complaint must show both the shortfall and its cost to you. Send a written demand to the provider first, quantify the loss, and then claim refund or re-service together with compensation for the harassment and the expenses the failure caused.
Before you start
- The contract, booking or engagement letter, the invoice for the service, and the payment proof.
- Any advertisement, brochure or promise that formed part of what the provider agreed to do.
- The record of what was actually delivered — reports, statements, delivery logs, photographs, or a technician's shoddy work reduced to writing.
- Your written complaint to the provider and its reply, if any.
- Documents that prove the financial loss — a fresh invoice to have the work redone, a bill for expenses, payslips if income was lost, medical bills where relevant.
Steps
- Test the deficiency, not the disappointment. Poor quality of a service, a delay the contract did not allow, a failure to deliver what was promised, or a charging of more than the agreed price are deficiencies. Being dissatisfied with a service you got as agreed is not. Write down, in one sentence, the standard the provider failed to meet and the clause or promise that fixes it.
- Fix the burden of proof early. The complaint must show the shortfall. Keep the booking, the timeline, the promised outcome and the actual outcome side by side. If the service was to be done to a professional standard, a rival quotation or an expert's opinion that the work was defective is worth more than your own assertion.
- Quantify the financial loss. Separate the loss into: the fee you paid for a service you did not receive, the cost of getting it redone, out-of-pocket expenses the failure forced on you, and any income you lost. Each head should tie to an invoice, a bill or a receipt. Vague claims of loss are trimmed by the commission.
- Send the notice before the complaint. Write to the service provider setting out the facts, the shortfall, and what you want — a full or partial refund, a re-service at no cost, and compensation for the harassment and expenses. Give a definite time to comply. The notice is not a formality; it often produces settlement and, if not, it frames the case and shows the commission that the provider had a chance to cure the fault.
- Decide the heads of relief. Ask for the removal of the deficiency, a refund of the fee, replacement of the deficient service, and compensation for the loss and the mental agony caused, as the Act allows. Interest on the amount wrongly retained may be claimed where the facts support it.
- Choose and file before the commission. The commission is chosen by the value of the services paid for, and the complaint may be filed through the e-Daakhil portal or at the commission's counter. Attach the notice and its proof of service, the contract, the payment proof and the loss documents.
Documents to keep
- Contract, booking form or engagement letter and the full invoice.
- Payment proof and any receipts for substitute or repeat work.
- The written notice to the provider and the postal or email proof of service.
- Bills, quotes and statements that establish each head of loss.
- Photographs or recordings of the defective work, dated and clear.
What goes wrong
- Calling a mere dissatisfaction a deficiency. If the service met the agreed standard, the commission will not step in. Anchor the complaint to a promise or a legal standard.
- No proof of loss. Claiming compensation without bills or receipts leads to a modest award at best. Keep every document that shows what the failure cost.
- Skipping the notice. A complaint filed without a demand may be adjourned while the provider is given an opportunity to reply, delaying you for months.
- Lumping all relief together. State each head separately — refund, re-service, compensation, interest — so that the commission can allow the ones that are proved.
- Ignoring the limitation. A consumer complaint must be filed within the period the Act allows from the date the deficiency arose, with an application to condone delay where the facts justify it.
Common questions
What counts as a deficient service?
Any shortfall in quality, in the nature of the service, or in the manner of its performance against what is required by law or undertaken by the provider. A hospital's careless treatment, a builder's failure to hand over, a coaching class that stops classes, an insurer that refuses a valid claim — each is measured against the promise made.
Can I also claim for mental agony?
Yes. The Act allows compensation for the loss and the injury, which includes the harassment and the mental suffering a deficient service causes, but the amount must be reasonable and supported by the facts.
Do I need to prove the provider was negligent?
Not in the criminal sense. It is enough to show the service fell short of the standard undertaken or required. Negligence, if there is, strengthens the claim for compensation.
Can I file if the provider is in another city?
Yes. As under the general scheme of the Act, the complaint may be filed where the opposite party works or carries on business or where the complainant resides or works for gain, so a consumer is not forced to travel to the provider's city.
