Boycott Booking.com, they don't care about their cudtomers

I booked an apartment using the Booking.com app, as always. The apartment that I booked was within my budget range, and I booked it for a month. The booking was confirmed after I had made my payment. It's one of those online payment bookings. A few hours later I receive a message from the property owner that the apartment is occupied and the tenant will check out on the 9th of February. The property owner continues to tell me that they have been communicating with Booking.com that they should block the dates, as I wasn't the only person who has been making bookings for that apartment. I have been on the phone with Booking.com since 11 until just now, 20:10 p.m., with 5 different consultants who told me 5 things. The second consultant sent me a link for an apartment that is slightly more expensive, by R2000, than the original price I paid, and upon approval, they had a system technical issue. The consultant after that one (3rd consultant) also sent me links of apartments to choose from, and also they were slightly more expensive than the original price and also had a system technical issue and dropped the phone. She followed up with an email that it is not Booking.com's responsibility to book me an alternative apartment if should book my own apartment. So in s nutshell, with all the hours I have spent with Booking.com consultsnts, my wasted time, I still don't have a place to stay. The last consultant told me to borrow the R18000 from someone so I can book an apartment as its not in their process to book me an apartment.
