Extremely Poor Customer Experience from The Mansion Lodge and Booking.com

Extremely disappointing experience with The Mansion Lodge and Booking.com. I made a reservation at The Mansion Lodge in Hartbee****rt for 11 to 13 September 2026. At around 1 PM on 10 September, less than 24 hours before check-in, I received a message saying they could not accommodate us due to flooding. No phone call, no assistance with alternatives, effectively leaving me to deal with the consequences through Booking.com. I spoke to three different agents. One was initially helpful and promised follow-up that never came. Today, two more agents listened but the calls appear to have been dropped without resolution. I am frustrated and disappointed because this was a last-minute cancellation, and I now need to find alternative accommodation at short notice. I would like The Mansion Lodge and Booking.com to urgently clarify the following. 1, why was the cancellation communicated less than 24 hours before check-in? 2, what assistance or alternatives should have been provided? 3, will I receive a full and immediate refund for the cancelled reservation? And 4, why has customer service not been able to resolve this despite multiple contacts? This has been a very poor customer experience from both parties.
