How do you respond to a 1-star review with no comment?

Short answer

Reply politely, invite the person to share what went wrong, and give them a direct way to reach you. A star-only rating leaves you guessing, so your job is to open a door rather than defend yourself against a complaint you can't see.

What to say

• Thank them and acknowledge the rating without being defensive.
• Say you'd genuinely like to understand what fell short.
• Offer a name and a direct contact so they can tell you privately.

Keep it warm and short — something like: "We're sorry to see this and we'd really like to make it right. Could you reach us at [contact] so we can understand what happened?" Prospects reading it see a business that cares even when it isn't told why.
