You are getting fake negative reviews

So work the routes in order, keep your expectations honest, and do not panic-pay anyone to make it vanish. Here is what actually moves the needle.

Work the routes, in order

• Document the wave first. Screenshots with timestamps, the reviewer profiles, the timing, and your own records showing no matching customer or job. This evidence is what every later step depends on.
• Flag with that evidence, naming the specific policy the reviews break, fake or no genuine experience, coordinated attack, off-topic. "This is unfair" gets rejected; "we have no record of this person and here is why the described job is impossible" gets looked at.
• Reply in public, calmly. Something like: we can find no record of working with you, but we would like to help, please contact us directly. The next reader learns more from that than from the one-star itself.
• Escalate the genuinely coordinated case to the platform's batch-report or support route, and, if a competitor or a pattern is clearly behind it, to the regulator, knowing that regulators pursue systemic actors, not your single review, so it helps the record more than it fixes your week.
• Consider legal action only for the serious case, a review falsely alleging fraud, criminality or dangerous work, where a court order can compel removal.

The limit, and the line

The hard truth is that some fakes you cannot prove will simply stay up, and the practical answer then is a steady stream of genuine reviews that drowns them out over time. Hold the line that runs through this whole site: act only against what is genuinely fake or abusive, never against an honest bad review, because trying to scrub real criticism backfires legally and with the next customer. And if the fake reviews come with a "pay us to make them stop" message, that is not a review problem, it is extortion, and it has its own page.
