The bot is wrong, vague, or hedging
Fix knowledge, persona, and recrawl so answers match the site.
The bot only knows what is in Knowledge for that website. If a page was not read, or the live page changed after the last read, the answer will be stale or missing.
Fix the source page (or add a manual FAQ), then Start crawl if you still have a crawl credit this period. Visitors can thumbs-up or thumbs-down a reply in the widget; you will see that vote on the chat. Flag the thread with Needs a better answer as a reminder list.
For voice: set Persona and Tone on Widget. Ask it to speak as staff if you want first person (“we deliver…”) rather than “the company delivers…”.
For prices: make sure the live page shows the price in text or a normal product/plan table, then recrawl. Do not expect the bot to invent a number that is not on the site.
For contact: it will offer buttons instead of pasting numbers. If buttons are missing, put a phone, email, or WhatsApp link on a public page and recrawl.
If visitors hit the monthly request cap, they will see a limit error rather than a normal answer — check Dashboard usage.
