About this complaint handling process flowchart

A complaint handled well can keep a customer. This flowchart gives agents a clear path: acknowledge quickly, investigate, resolve or escalate, and confirm the customer accepts before closing. The last step records the root cause so the same complaint happens less often.

It fits support, retail and service teams. Add regulatory steps if your industry has complaint rules.

Step by step

1. Log. Record the complaint and acknowledge it.
2. Investigate. Find out what happened.
3. Resolve or escalate. Agents resolve what they can; the rest goes to a manager.
4. Confirm. If the customer doesn't accept, a complaints lead reviews it and a revised resolution is offered.
5. Learn. Record the root cause before closing.

How to make it in flow-chart.io

1. Start from the example. Edit the text in the generator box above so it names your own complaint categories and escalation rules, then press Generate. The free preview needs no sign-up.
2. Add the branches. Add the decision points that matter for you, for example refund above agent limit? or legal threat?. Each decision becomes a diamond with labeled outcomes.
3. Assign owners. Save the diagram to the editor (free account) and rename steps to show who does what: support agent, team lead and quality team.
4. Share or export. Share a read-only view link: people with the link can view the diagram but not edit it. Downloads as PNG, SVG or PDF are part of Flow Pro (see pricing).

Tips

• Set a target time for acknowledgment.
• Give agents clear limits on what they can offer.
• Review root causes regularly.

Frequently asked questions

What should be recorded?

The complaint, the customer, actions taken, the resolution, and the root cause.
