My Booking made 18th April 2023

I made a booking for 25 Idmiston Road in London for 22nd - 25th May 2023.

Payment was reserved on the 18th then taken on the 5th May. I then booked car hire which I received 10% discount for already making a booking.  All Good.....NOT

I have sent booking.com numerous e-mails asking for confirmation that the booking has been made and to send me a ref number.  I have been given a contact phone number but only if I have a ref number.

Can anyone please help
