Steps to Submit a Complaint Online

Follow these steps for the best chance of a resolution:

  1. 1

    Identify the problem – Note what went wrong and what outcome you want (refund, replacement, correction).

  2. 2

    Gather evidence – Save receipts, screenshots, emails, and photos related to the issue.

  3. 3

    Find the official complaint channel – Use the company's website, app, or listed support email.

  4. 4

    Write clearly – State the facts, include order or account numbers, and specify your desired resolution.

  5. 5

    Submit and save your reference number – This proves when you filed and helps with follow-up.

  6. 6

    Follow up if needed – Wait a reasonable period (often 7–14 business days), then reference your original complaint.

What to Include When You File a Complaint Online

A strong complaint against a company answers the questions a support agent needs before they can act. Before you register a complaint online, make sure it includes:

  • Your name and the email address or phone number linked to your account.
  • The order, invoice, booking, or account number.
  • Key dates: when you made the purchase, when the problem started, and when you first contacted the company.
  • A short, factual description of what went wrong.
  • Any earlier ticket or complaint reference numbers.
  • The resolution you want and a reasonable deadline for a reply.
Sample complaint message

Subject: Complaint – Defective blender, Order #A-104829

I bought a blender from your online store on September 2 (Order #A-104829). It stopped working on September 10 and will not power on. I contacted your support team on September 11 (Ticket #55120) but have not received a reply.

I have attached my receipt and a short video showing the fault. Please issue a full refund of $89.99 to my original payment method, or send a replacement, within 14 days.

Thank you, [Your name] – [Email or phone]

Caution: Never include passwords, OTPs, PINs, or full payment card numbers in an online complaint.

Where You Can Complain About a Company

Depending on the situation, you can raise your complaint directly with the company, through the platform you purchased from, with your bank or card issuer for billing disputes, or with an appropriate industry regulator or consumer protection organization.

  • The company itself: Start with its customer support, complaints team, or escalation desk. Most issues are resolved at this stage.
  • The platform you bought from: Marketplaces and app stores often run their own dispute or buyer-protection process for a complaint against an online seller.
  • Your bank or card issuer: For billing errors, unauthorized charges, or paid-for items that never arrived, you may be able to open a payment dispute. Time limits apply, so act promptly.
  • A regulator or consumer protection body: For example, in the US the FTC takes reports about fraud and unfair business practices, the CFPB handles bank and financial complaints, and the FCC handles telecom complaints.

Common Types of Company Complaints

The consumer complaint process is similar across industries, but the evidence that matters most changes with the problem:

Common Mistakes to Avoid

  • Being vague instead of specific about the problem
  • Skipping supporting evidence
  • Using aggressive or threatening language
  • Not saving your complaint reference number

What If the Company Doesn't Respond?

If you don't hear back, send one polite follow-up referencing your original complaint. If the issue remains unresolved, you may be able to escalate to your bank or card issuer, or to a regulator or consumer protection body relevant to your situation and jurisdiction.

Sample follow-up message

Subject: Follow-up – Complaint reference SC-20418

I submitted a complaint on September 12 about Order #A-104829 (reference SC-20418) and have not received a response. Please reply with an update within 7 days. If the issue is still unresolved, I will escalate it to my card issuer or the relevant consumer protection authority.

When you escalate, attach your complaint history: the original message, your complaint reference number, the follow-up, and any replies. A clear paper trail shows you gave the company a fair chance to fix the problem.
