I received notification for a booking in San Diego for “my nephew and niece” (neither of which I have) and that I was charged £427. Luckily the credit card company has taken this seriously. We did not make a booking. The apartment owner has got the police involved and is endeavouring to sort something out on his end. Our rant is that there is no phone number for guests, only (I assume) for hosts to contact Airbnb. What a strange and rather ridiculous way to run a company. Anyone buying a service should have recourse to contact the company. Does anyone have an explanation as to why they don’t want to be contacted? I don’t think I have come across a company without a customer service line before. I am concerned that whoever did make this booking may be tampering with bookings I have actually made for later in the year. Any advice would be most welcome so that I can get some reassurance from Airbnb about how the company handles privacy settings and all our details.
