How do you catch unhappy customers before they leave a public review?

Short answer

Give customers an easy private way to reach you and make follow-up fast, so problems surface to you directly instead of only on Google. Just don't use that channel to block unhappy customers from reviewing publicly — that's gating.

A fair approach

• Offer a simple "How did we do? Tell us directly" path alongside your public review ask.
• Respond to private complaints quickly and fix them.
• Still let everyone leave a public review; you're adding a channel, not filtering one out.

Resolving issues privately and promptly naturally reduces angry public reviews — not by hiding them, but by fixing the experience before frustration boils over.
