Missing bookings

I booked accommodation that does not show up on my profile. Now there is a dispute and I cannot access dates, details, and communication with the property. Even when I put in the confirmation number and pin, the booking comes up but not the messages and when you refresh, the booking disappears. I suspect it's because it's an 'external service provider.' But what's the point of the app if all the details of your booking and communications aren't available easily and conveniently in one place? The inconvenience of multiple emails when travelling is one of the reasons I booked through booking.com.

And if the accommodation doesn't reflect on your profile you can't ask for help with it. Ridiculous!
