How to file an ISP complaint with evidence.

A complaint without records becomes "a problem with your equipment". A complaint with dates, times, durations and exactly what failed becomes a technical ticket — and backs the next one, with your regulator or consumer protection.

1. Record the drops for a few days

Keep the recorder on and mark each incident as it happens. Two or three episodes with exact times are worth more than a week of impressions. Each mark produces a folder with a plain-language report, all the measurements and a ready-to-attach ZIP.

A one-page report.pdf, ready to attach to the ticket, already comes inside every incident bundle.

2. Open the ticket with the data

When you contact support, give exact dates and times, durations and the observed pattern — for example: "the router responded while external targets failed". Attach the report and ask for the reference number; the next step requires it.

3. Still unresolved? Escalate

With the ISP's reference number and your records in hand, file the complaint with the official channel in your country. In Brazil: Anatel, the telecommunications regulator (reachable on 133 or on its website), plus Procon or consumidor.gov.br for consumer protection. Elsewhere, the equivalent is your communications regulator.

4. Attach what it shows — and stay honest

Your records show what this PC experienced, with explicit coverage windows. They do not identify the responsible component. Saying "the measurements show repeated drops between my equipment and the tested destinations, with the router responding" is strong and defensible; saying "the ISP killed my internet" is not what the data proves.

A second device measuring the same network answers the question support always asks: if the failure hits other devices too, it is from the home outward.
