THEY ARE THE WORST WITH FLIGHTS, NEVER EVER BOOK WITH THEM

Never ever book a flight with booking.com!!! I struggled to change my return flight from JHB to Dubai, I had to purchase another one way flight and guess what when I was returning I had to purchase another one way flight. They said they would refund me, after a few months of struggling with them I gave them my new bank account and they told me they want the old account(which I closed and couldn't reopen it). THEY ARE THE WORST WITH FLIGHTS, NEVER EVER BOOK WITH THEM. I lost R8715.35 for ticket and R2500 ticket change. It's been over a year now still nothing, I sent them my personal bank details and they would reply to say it was processed.
