the commission is deducted from me, but the client did not arrive

Hello, they booked my house but I didn’t have a card added, that is, they booked without prepayment, they were supposed to arrive on February 1 but they didn’t arrive, I clicked as a no-show, but booking takes a commission of 46 euros from me, but they didn’t send me money and I’m new in booking, what do I need now do?
