Sorry for you, @Mohammad-Reza0. The domain name from the website you used, is longterm-rental dot com. I spell it differently, as I do not want to create a link to them.
Everyone can buy this domain or thousends of variants of that. Nobody could keep a fraudster from buying it.
And after creating this longterm... domain, they add airbnb as a subdomain. It’s intentionally, as Robin says, to create the fraud.
Only the domain owner can decide what and if to use subdomains. It’s not possible to keep it from happening. When it’s used for a fraud and using the airbnb brand, they can try to do something against it, but if it’s registered in a country with loose laws, it’s impossible to do that quickly.
As said, you transferred money to someone, who has nothing to do with airbnb and probably nothing with the original listing. Those people just copy pictures or whole listings. Contact your bank immediately. If you paid by card, you have some hope, if you transferred it, not so much.
