@Andy2459 What it sort of sounds like is that someone has hacked your Airbnb account with the email address you rarely use and created a duplicate listings which may have been reported to Airbnb as a scam. If you can access that duplicate account, check the payout information on it- it may have been changed to direct payments to a scammer's account.
Unfortunately there's nothing anyone on this discussion forum can do to help you with all this- you're just going to have to work with Airbnb to get to the bottom of it.
