for this reservation 3153768927

Hello,
This reservation has been canceled, no one has come on behalf of this person. but the client did not cancel it in the system,
since it is new to me as a site, I did not know how to cancel it as a reservation.
Why do I have to pay a commission for a reservation that did not make the payment?

Waiting for your reply
