They just wont give me my refund

Booking ref number *** I made this booking at the beginning of June through booking.com and as part of the conditions, this booking was subject to free cancellation provided it is done before the 22nd of July. After my travel plans changed, I requested for a cancellation on the 24th of June, which was well ahead of the allowed period for this free cancellation. I got the confirmation that my booking was cancelled on mail, but no contact was made to let me know how I will get my money.after a lot of chasing on emails, a lady by name of Esther Engelbrecht eventually responded to my mail on the 5th of July offering another date. I immediately responded and told that Dulstroom was no longer on my plans. She only responded on the 12th of July telling me that she would be touch once she had received the refund date, from who exactly, I dont know. My money was taken immediately after I made the booking, but I am wondering why I should wait for 2 Months to get my money back, it is frustrating. Please assist
