I am so upset as I made a booking via the website and as such was advertised that I could pay at the resort just as I am getting ready to go on our stay ,I get a reminder of my booking just to check on the booking.com app that my booking had been cancelled,I am infuriated as this was meant to be a birthday celebration and so I called the customer service line waited in a queue for 15 minutes and the advisor then transfers me to AKTV Goudini Spa ,where a very helpful and friendly Mrs Jacobs explains to me that a payment is required ,what false advertising from booking.com and Bad Customer Service as the advisor just passed the buck. I am very disappointed with booking.com and this was my first experience which was so horrible, my booking was cancelled without me knowing as I saved it in my calendar and now been reminded just to discover it had been cancelled and I never saw that email
