Booking.com Refund For Accommodation

I made a hotel reservation in India through Booking.com with check‑in on 31/12/2025 for a one‑week stay. Due to the terrible condition of the accommodation, I was forced to leave early and checked out on 03/01/2026, even though I had paid for the full week, which was approximately £600. The accommodation was unacceptable in every respect, including cleanliness, safety, noise and the general condition of the facilities, and it did not match what I expected based on the listing on Booking.com. Because of these issues, I did not feel comfortable or able to stay for the full duration and had no choice but to leave early. I contacted Booking.com customer service about this and was told that I would receive a resolution within three days. It has now been around two weeks and I have not received any further response, email or message from Booking.com or the property. I am requesting a refund for the unused nights of my stay due to being forced to leave early because of the poor and misrepresented accommodation, and I also ask that my case be reviewed urgently, as I have already been waiting far longer than the timeframe Booking.com promised.
