Airbnb False Advertising

Good day I had a terrible experience with Airbnb I booked one of their places for 10 people at a certain price made the payment and a hour later the owner called me to say the price I paid is only for 1 person . I then contacted Airbnb and they just cancelled everything and said there's nothing they can do the owners of the place made the incorrect adverti*****t. Is this not false advertising? Because why was it not corrected? I feel that I was unfairly treated and should be allowed to go on my holiday which I booked for 10 people!
