***** by booking.com a disgrace

I bought flight tickets from them for R4 036, the price given in writing, but they charged R18 184 on my credit card. This is the biggest ***** and **** I have ever encountered. Do not book with them because you will lose a lot of money. They told me in writing that the first amount is the full and inclusive cost of the flight tickets. They are *****ing from the public, and we, as the public, have no recourse at all. Furthermore, they are extremely difficult to contact, so they hide behind the internet. Stay away from them!
