Fake reservations in my apartment

Dear booking service,

please I would like to ask you to call me back on my telephone number: ***, because of your customer number does not exist anymore (***)

In last one month I have received 3 or 4 reservations and nobody come to our apartment and it was not possible to contact the guest. Thatswhy they booked my terms..

Can you please call me back or send me your new telephone number on which I can reach you?

Thank you in advance.

Veronika
