Confirming bookings at Guesthouses that are not accepting any guests

I made a reservation for the 24th of January 2025 - 26th January 2025 for two nights at the Urban Sanctuary Hotel, Johannesburg which was confirmed and debited from my account. On the 24th as i was on my way to Joburg, I called the property owner who indicated to me that he was no longer taking guests as the property was under renovations as a result he could not assist. I had to make alternative plans and later logged a query with Booking.com to which they responded with the below :-

We have contacted The Urban Sanctuary Boutique Hotel & Retreat regarding the concerns about your reservation status, and they have confirmed that it remains active and unchanged. They will be waiting for you on Fri, 24 Jan 2025. Partner response If you'd like to contact the accommodation directly, you may call them at +***5 or send them a message. If you have any other questions, we are always here.

Mind you the query was in March they continue to indicate that the booking is still secured for the 24th.

To this date I have not received my refund.
