After we made the payment, the company staff asked my private email address and ask me about the detailed bank information which I think is not safe, because anyone know all the information can use my card easily. so I didn't give the detail information ,and they told me if we don't give that information , we need to arrive there between 3 pm to 5 pm. After we arrived at the reception, they use ￡100 of my card for pre-authorisation. I booked from airbnb lots of tiems, and this is the first time that I was asked to do so.
