How are businesses supposed to deal with Trustpilot reviews they can’t verify?

I handle Trustpilot reviews for a business and this is becoming one of the most frustrating parts of the job.

We occasionally get negative reviews that don’t match any customer, order or support interaction we can find. We request more details, flag them, provide context, and sometimes Trustpilot still leaves them up.

At that point you’re stuck between two bad options: leave a review you genuinely can’t verify, or keep burning hours on disputes and appeals.

For anyone managing TP for a business: how do u handle these cases? Do u keep everything in-house or eventually bring in outside help?
