Booking.com Credit Card *****

I made a booking at San Lamer for the 15th-18th Aug, pre-booked using my credit card. Received confirmation etc. no hassles. On the 30 July 4 unauthorized amounts get taken of my card amounting to R31000.00 I contact the bank to cancel the card and Booking.Com to report that they have taken the amount off my account and should refund the money. Firstly it's a nightmare to get the helpline no. then the call Centre agents can't really help you. I was told via email that they admit the money was taken off in error (after sending bank statements several times) However they can only refund in the next 21 days. They sent the host an email in the mean time saying that they will refund the money to her account to then transfer to me. Which I don't have an issue with but this never happened as she was paid out what was due to her and never received my refund. She contacted me with this info and asked me to follow up with them. Painstakingly I contacted them and was told to wait the 21 days, to which I explained what the host's email said. So now I'm going to wait again lets hope this time they keep their word. By reviewing the sheer number of disgruntled reviews here it's a no brainer that this is an extremely un-trustable company. I will never use them again
