Unexpected arrival???!!!

We had a guest arrive yesterday evening that was totally unexpected as our property show we are 'Not Bookable' on Booking.com!!??

Their details are :-

Name - ***

Conf. No. - ***

16/07/2020 for 4 nights - Grand Apartment.

Can you tell me how it's been possible to book this directly with you or was it via a sub agent?

How do we receive payment and how much have you charged?

Can someone call me on *** and email me on ***

Thank you.
