Write a broadband complaint backed by evidence
A clear message helps your provider understand what happened and what you are asking it to investigate.
What to check
Record dates, symptoms, results, test conditions and exact plan wording. Keep prior support conversations and reference numbers. Describe what you observed without asserting an unverified cause.
What to do next
Ask the provider to investigate and give you a complaint reference. If it remains unresolved, check the official complaint route for your location.
