Booking.com goes Awol (with customers money) during Covid-19

My wedding was set to take place in June 2020 so I booked Sheffield Luxury Beach Villa in Ballito to accommodate my family and myself as it's quite close to our wedding venue. The booking was made on the twenty seventh of January this year, I got a message on the twenty fifth of March from the owner Luca of the accommodation stating that they had sold the property and that I need to cancel my booking and rebook with the new owners, I was assured a full refund from them. I ended up getting half of my money back from the 'previous owners'. After contacting Luca about the other half, he mentioned that booking.com would do a refund of it and that they have been informed about the situation. Over a month later, I contacted him again to let him know that I still have not gotten my full refund: "Everyone else has been fully refunded, try to contact them yourself and if you are lucky enough to not get a machine, let us know" was the response I got. After going through the online reviews of so many people who are voicing their anger and similar experiences with booking.com I am beginning to grow increasingly concerned about the integrity of this booking facility. I am beyond frustrated and feel like I've been ****med out of a lot of money. I understand that Covid-19 has now completely taken over our lives however, you've taken our money so you have an obligation to provide a service or return our money to us if you can not live up to your end of the deal! At the very least communicate with your customers!!!
