Booking.com ****ming customers- DO NOT USE THEM!

Booking.com is ****ming customers by not updating bookings on the app. As a customer, you remain confused and unknowing if a booking has gone through which leads to double booking resulting in one having to cancel one at a later stage and being charged full cancellation. The app did not show the booking I already did for the shuttle service from Golden Tulip Hotel to Zanzibar airport.

The morning of the trip, my booked shuttle was still not showing and out of panic, I booked another trip from Golden Tulip to Zanzibar airport now having two trips on the same day, same time to the same airport. The morning booking costing almost twice due to the demand. Only after I booked the trip, now both trips were showing. I tried to contact the Team without much success or assistance from booking.com Team. I had to cancel the shuttle booked in the morning but the Team is refusing to refund me although it's their app that was faulty and not updating booking or sending confirmations via email as they normally do.
