No customer service

I booked a family room for my wife and children through Booking.com for 30 and 31 December 2024. On arrival at Versailles in PTA, they found that the room looked nothing like the pictures and there was no water, electricity, towels or even toilet paper! I contacted the "owner" but his cell number and email was not active so I could not speak to "Terry" and the "manager" said we should speak to the owner. I contacted booking.com asking for a full refund they rep**** I need to contact the owner so no luck with that. I am very disappointed because booking.com don't vet the establishments and I had find other accommodation for my family, pay for it and they didn't even stay in the booked room!
