False advertising

Recently booked a stay with Airbnb with a host named Jason, the stay was R1120 for two nights at the point waterfront in Durban. As it was advertised, I booked and paid the price, two days before my arrival. I get a call saying that the price of the unit was advertised incorrectly and that my reservation would be canceled if i did not pay an excess of another R2000. We would be traveling from far and to get your reservation canceled was totally unacceptable and ********* considering that it was not in anyway my fault that the pricing was incorrect. Very disappointed and upset.
