Fix Vapi Voice Bot Booking Issue

I have a Vapi voice bot that handles calls and books appointments through Google Calendar via n8n. The bot works well overall, but it struggles with relative dates and times like “next Tuesday” or “tomorrow afternoon,” sometimes booking the wrong date or failing to book. I need someone to troubleshoot and fix the existing setup, whether the issue is with the Vapi prompt, date/time handling, or the n8n → Google Calendar workflow. Looking to get this fixed quickly. Previous experience with similar voice bot booking issues is a plus.
