When my own tour booking went missing, I delved into viator reviews and spotted that visitors flagged missing confirmations when they included booking date, paid amount, and email used—all within one message. Taking that advice, I sent a clear follow-up outlining my traveler name, tour date, booking cost, and a screenshot of the blank reservation page. Within a few hours, I received an email containing the confirmation code and link to the full itinerary. Presenting full booking data in one go appeared to trigger their system to automatically fetch and send the missing confirmation. It saved my trip planning at the last minute!
