INCORRECT PRICES GIVEN

I made a booking with Ritsako game lodge via afristay.com and was told to pay a deposit of R3400, even received emails and sms confirming the amount I needed to pay... I paid the amount and got a confirmation about my booking, suddenly i get a call telling me the amount they provided was incorrect because they did not update their pricing on the web and that is not my fault... I just want them to fix it and I wanna see myself staying at the lodge with the amount they told me to pay, I am not happy with the service they have provided me.. i did my part as advised so they need to fix this.
