Complaint to Internet Provider Slow Speed

When and how to use this letter

File this complaint in writing through the provider's official support portal or email, and keep the ticket number — phone agents' promises evaporate, written tickets do not. Before writing, gather a week of speed tests at different times of day, run over a wired connection directly to the router, with timestamped screenshots. Wi-Fi speeds vary with interference; wired tests prove the line itself is underperforming.

Quote your plan's promised speed against your measured speed in the letter — the gap is your leverage. State how the slowdown affects you: remote work, online classes, streaming. Mention any technician visits or previous complaints and their ticket numbers, because a history of unresolved complaints strengthens your position considerably.

A non-obvious tip: explicitly ask for two things — a technical resolution deadline and a bill credit for the period of under-delivery. Providers rarely volunteer credits but frequently grant them when asked with evidence. If there is no meaningful improvement within 30 days, escalate to the telecom regulator with your test logs and ticket history; regulators act on documented patterns, not angry phone calls. As a last resort, the documented speed shortfall is usually valid grounds to cancel without early-termination fees. Keep all your evidence organized in one folder — dated speed tests, ticket numbers, call logs — because a well-documented complaint is resolved faster than ten angry phone calls.
