Horrible service from Booking.com

On the 19th of November, I made a reservation on Booking.com for an overnight stay at Going Places Bed and Breakfast in East London. I requested that money be deducted from my account at a later date by the property. Almost immediately the money was taken from my account. One of the main reasons I requested that the money be deducted at a later stage was because I did not have enough funds in my account, additionally, I have always paid for my bookings at a later stage. I canceled the booking after they debited my account and disputed the transaction on my banking app (FNB). Booking.com has not assisted me in resolving this. Instead, they've given the property an additional 5 working days to action the reversal. Oh and yes, my ban FNB has been sending me from pillar to post. I've incurred ridiculous charges because of this! All I want is for the funds and charged to be reversed.
