Booking.Com get back to me!!!

Good morning I’m writing in behalf of Sakhumzi On the 26 December I did a booking with booking.com When we get to the hotel it’s full but they already deducted the money from my account. When I enquire why did they deduct but it’s full I was given customer service number. I called them and I sent several emails but I was told to wait for 14 days for refund it’s almost a month now I’m still waiting for my refund. Booking.com I will never ever use your services I WANT MY REFUND!!! I will go further with this matter.
