Well, I can't keep it if I book it online.

What you want to ask is why you can't check in after booking online? There are too many loopholes. The inquiry website shows that because there are too many loopholes in the good reservation system, consumers can't pay in advance to enter the hotel account, which leads to the reservation room can't stay. You can defend your rights and ask the hotel to double the deposit and compensate for the economic losses caused.
