Need refund and contact information

<p>To whom it may concern,</p> <p> </p> <p>I am used to using websites like bookings.com ect and recently heared of airbnb. I wanted to request availability of 2 accommodation locations for 3 couples later this year. The other websites normally would come back with reservation is available would you like to book? Not airbnb. Immediately after my requsts a payment of R11337 went of my bank account to my shock. Luckily I could stop the other reservation otherwise I would of made two bookings. I wanted to cancel immediately as I just wanted to check availability we are not certain of dates and amount of people yet. So obviously this was a shock. I immediately contacted the host and explained my situation as this is the first time I am using the app and I miss understood the request, but she said I should contact airbnb itself. My second problem is that I cannot find any contact information of airbnb on their website? There is no email adress that I can contact. I see that I am supposed to get a full refund if I cancel within 24hours, but if I try to cancel on the website then I will pay R5000 cancellation fee. How does this work? I do not know what to do.</p>
