Booking.com never notified accommodation of my stay and accommodation already full.

I made a booking for accommodation for 26 April 2024 at a guesthouse in Potchefstroom. However, when I arrived at the accommodation they were never informed by booking.com of my stay. We were only sleeping over one night and the guesthouse were already fully booked and also the surrounding accommodation as there were a large sporting event taking place at NWU. I then tried to call booking.com to get a resolution and help. After holding on for more than 25 min and no answer I gave up. Then tried the message service of booking.com to see if I can get help there. However, the service from booking.com is so bad I got no reply. The first reply I got was to rate my stay at the guesthouse the next day. However, as I did not stay there how can I rate the stay. Booking.com then only rep**** on the message on 28 April 2024 to say they had huge call volumes and that is the reason they could not answer my call and they will discuss with the accommodation on what happened.

After this I got a reply from Hannes on 6 May 2024 to indicate that I must contact booking.com during my stay and they can do nothing afterwards. What a **** reply as i did send them a message and also tried calling without out an answer on the day of my stay. I will recommend to everyone not to use booking.com. When something goes wrong on their side they cant help you and this is also an indication of why they have huge call volumes and could not answer.
