Booking.com Hotel Reservation Cancellation and Full Refund Request

I made a reservation at a hotel through Booking.com and contacted them yesterday with a simple question about my room. I wrote to them many times, but they did not give me any answer and their attitude felt very rude and dismissive. Because of this behavior and the complete lack of response to my messages, I no longer feel comfortable staying at this hotel. I want my reservation to be cancelled and I am requesting a full refund with no charges or penalties, as I believe I am being treated unfairly and with disrespect. I ask that my situation be reviewed and that my reservation be cancelled with a full refund as soon as possible.
