Very difficult to speak to an agent at Booking.com. Both as an owner and as a guest

Booking.com itself works wonderfully. No complaints there. But recently, I as a guest wanting to book and trying to get hold of the call center, takes more than 30 minutes holding time. And then if you are fortunate you will be put through to someone after 30 minutes of patience.... But I have also experienced that after 30 minutes waiting anxiously that the line got disconnected. :( Then I had to start the whole process of 30 minutes waiting again. Which is horrible. Especially if you are phoning from an (overseas) mobile/cellphone number....
