Booking.com Lost Booking Reference for Hotel Reservation

I made a hotel reservation through Booking.com for a stay from 4 to 11 November 20216 with an approximate total cost of around £1,300, using the email address MARIN***@BTINTERNET.COM. I have lost my booking confirmation number and I am currently unable to log in and access my reservation details. I first contacted Booking.com customer service about this yesterday and received a reply today. In my message I clearly asked them to provide my booking reference number so that I could access my booking. However, instead of giving me this information, the response only requested many additional details and did not contain any useful or practical information that would allow me to retrieve or view my reservation. I am very concerned as my stay dates are approaching and I still cannot access my booking. I request that my booking reference number be promptly shared with me and that I be provided with clear assistance from a human agent so I can log in, review, and, if needed, manage my reservation without any further delays.
