Airbnb stole my money!

I tried to make a first booking on Airbnb and had my reservation in Kent accepted and confirmed. Without telling me, Airbnb cancelled my booking and told the host that I was a fraudulent account and not to accept me as a guest. The host then rented out the room for my dates and it wasn’t until a couple of days before arriving when I called the host for instructions on how to get there, that they told me this.

Much to my annoyance Airbnb took the money anyway not giving any to the host and as yet haven’t given any of my near £300 back.
Doesn’t matter what country you’re in, this is theft or at the very least fraud. They as a company have obtained my money by deception and are refusing to give it back. The customer service line is useless and there’s no other person I could speak to having been told ‘this isn’t my department and I can’t help you’. Next stop for me I suppose is the police!!
