📋 Complaint summary

Customer reports being charged for both the old (Professional) and new (Enterprise) subscription tiers in the February invoice, despite upgrading on 15/01/2026. Total overcharge: €247. Customer has contacted support twice previously (tickets #8901, #8934) without resolution.

🔍 Investigation

  • Confirmed upgrade processed on 15/01/2026 in CRM (order #EU-2026-4421)
  • Billing system shows two active subscriptions: Professional (auto-renewed 01/02) and Enterprise (started 15/01)
  • Root cause: upgrade workflow did not trigger cancellation of the previous tier — known bug in billing API (JIRA BIL-892)

✅ Resolution

  • Issued credit note for €247 (CN-2026-0089) — applied to March invoice
  • Manually cancelled legacy Professional subscription in billing system
  • Sent apology email with confirmation of credit and correct billing going forward

🛡️ Preventive action

Engineering fix: JIRA BIL-892 escalated to Sprint 14 (ETA: 28/02/2026). Fix will auto-cancel legacy subscription when upgrade is processed. Interim: Support team to manually verify subscription status for all upgrade requests until fix is deployed.

What is a complaint handling template?

A complaint handling template is a structured format for documenting customer complaints — capturing the issue, investigation steps, resolution, and root cause — so every complaint receives consistent treatment and the organisation learns from recurring problems.

Complaints are a signal, not just a problem. Each one reveals where the product, process, or service failed from the customer’s perspective. Without a structured template, complaints are handled individually and forgotten once resolved. The same issue surfaces again, handled differently by a different agent, with no trend data for the team to act on. A template captures every complaint in the same format — making patterns visible, resolutions consistent, and systemic issues identifiable.

Who should use this template?

This template is for teams that receive and resolve customer complaints:

  • Customer Support Managers — ensure every complaint follows the same investigation and resolution process
  • Quality Assurance Teams — analyse complaint data to identify recurring issues and drive process improvements
  • Compliance Officers — maintain an auditable record of complaint handling for regulatory requirements
  • Product Managers — review complaint patterns to inform product improvements and prioritise fixes

What’s included in this template?

The template has two parts: structured metadata fields and the complaint record.

Metadata fields classify each complaint:

  • Complaint reference number and date received
  • Customer name and contact channel
  • Product or service involved
  • Severity (critical, high, medium, low)
  • Status (received, investigating, resolved, closed)
  • Assigned handler

Complaint record documents the case:

  • Complaint summary — what the customer reported, in their own terms
  • Investigation — steps taken to understand the issue, including evidence gathered
  • Root cause — the underlying reason the issue occurred
  • Resolution — actions taken to resolve the customer’s specific complaint
  • Preventive action — changes to prevent the same issue from recurring

How to create and customise this template in Elium

  1. Open the Template Builder — Go to your profile menu and select the Template Builder tab, or click “+ Create” and choose “Create a new template”.
  2. Set the scope — Choose an icon, enable the template, and decide whether it applies platform-wide or to specific spaces (e.g. your Customer Service or Quality Management space).
  3. Add structured fields — Click “Field” to add metadata: text fields for reference number and customer name, tag fields for channel, product, severity, and status, a date field for date received, and a user field for assigned handler. Mark reference number, severity, and status as mandatory.
  4. Build the record structure — Use the “+” button to add content blocks: text blocks for complaint summary, investigation, root cause, resolution, and preventive action. Add placeholder prompts (e.g. “What did the customer report in their own words?”).
  5. Preview and save — Review the template layout, then save. Agents can now document complaints consistently, and you can apply it to existing content in bulk.

How AI helps you create and use this template

Capture faster. Paste a customer email, chat transcript, or call notes into Elium’s AI. It identifies the complaint, affected product, and severity — then drafts a structured record that the handler reviews rather than transcribing manually.

Retrieve smarter. A quality manager asks Elium’s AI: “How many complaints about delivery delays have we received in the last quarter?” The AI returns the relevant complaint records with root causes and resolution outcomes — turning raw data into actionable insight.

Why teams use Elium for complaint handling

Complaint data is only valuable when it is structured enough to analyse. If complaints live in email inboxes or ticket comments, patterns stay invisible. Elium makes complaint data searchable and structured: templates ensure every record captures the same fields, tags enable filtering by product or severity, and AI surfaces trends from historical complaints.

By structuring service processes in a single platform, they achieved 80% first-contact resolution and reduced call handling time by 10%, ensuring complaints are handled consistently across every channel and site.

Frequently asked questions

Complaint handling is the process of receiving, investigating, resolving, and learning from customer complaints. Without a structured approach, complaints are resolved individually with no trend analysis. A template ensures every complaint is documented consistently — creating data that reveals recurring problems and drives systemic improvements.
A complete template includes metadata (reference number, date, customer, channel, product, severity, status, handler) and a record covering complaint summary, investigation steps, root cause analysis, resolution actions, and preventive measures. Each field should be searchable so teams can analyse patterns across complaints.
Structured complaint records reduce resolution time because handlers follow a consistent investigation process rather than improvising. They improve customer satisfaction because resolutions are thorough and include follow-up. They drive product improvements because recurring complaints are visible and measurable rather than anecdotal.
Acknowledge the complaint immediately and set expectations for response time. Investigate the root cause, not just the symptom. Resolve the customer’s specific issue, then document what went wrong and why. Implement preventive action so the same complaint does not recur. Close the loop with the customer.
A support ticket tracks a request for help — it may or may not involve dissatisfaction. A complaint specifically records customer dissatisfaction with a product, service, or experience. Complaints carry additional requirements: root cause analysis, preventive action, and trend monitoring. Not every ticket is a complaint, but every complaint should generate a ticket.
