Booking cancellation

I booked a stay via booking.com with the Blyde ,one bedroom apartment , from 30.12.21 to 02.01.21 . I was ordered to pay 80 % deposit to secure the apartment as is high peak season , I paid the amount requested to Luke Nene and sent him proof of payment , the payment time was within 12 hours of my booking . I got an email notifying me that my booking has been cancelled on the 24th Dec 2021 , with no clear reason as to why , and no mention is made of my payment refund . Please can Luke Nene refund my money , within 12 hours of cancelling my booking as he requested me to pay with a time frame . I sent him my banking details. What an inconvenience .
