This kit covers three related problems with a broadband, mobile, landline, energy or water provider: an overcharge or billing error, a disconnection (or a threatened one), and a service failure that isn't being fixed. Start with the complaint generator and pick the scenario that matches your situation — it writes a different letter for each — then use the evidence templates and checklists alongside it to back up every figure you put in the letter. Every generator, template and checklist below is completely free to use — no account, no payment, no catch.
The sequence
Pick your scenario in the generator first, then gather the evidence that supports it before you send the letter.
Step 1 · Pick your scenario
Write the formal complaint
Choose billing error or overcharge, disconnection or threatened disconnection, or service failure or outage. The letter sets out the facts, lists exactly what you want the provider to do, and names the ombudsman or regulator you'll escalate to in the US, UK, EU or Australia.
Step 2 · Back it with evidence
Prove what you were overcharged
Document the wrong charge line by line against your contract, check energy or water bills against your actual usage, and keep your own photographed meter readings so an estimated bill can't go unchallenged.
Checklists to use alongside
Free, interactive checklists to catch the error before you dispute it — and, if you're facing a shutoff in the US, what to check right now.
