Nightcap at Manhattan Hotel

Because this was the only hotel within walking distance from my friend's house, we stayed for a total of 4 nights and booked a 2+1+1 deal. Before checking in on the first day, the room fee and a deposit of 100 Australian dollars were charged to my credit card. On the fourth day, I went to the front desk to renew the room card (I couldn't open the door without renewing it). The front desk already knew that this was a prepaid order and asked if the payment would be deducted from the original credit card (I changed the name of the booker on the fourth night but didn't change the room and noted "extend stay" in the order). I thought that after the prepaid order, the hotel might have to charge a deposit again because the name of the booker had changed, so I replied "yes". As a result, not long after, the front desk deducted 157 Australian dollars from the credit card again. I returned to the hotel in the evening and called the front desk. The front desk said it might be the deposit and asked me to talk to the manager tomorrow. I checked out very early the next day and the front desk was not at work. I negotiated with the hotel through text messages. The hotel said that I booked the room twice, once at the front desk and then again on Ctrip two hours later. They were so shameless. I booked the room on Ctrip one night in advance, but I didn't go to the front desk to renew the room card until after 9 o'clock the next day. After the communication failed, I had to contact Ctrip. If the negotiation with Ctrip failed, I would post a complaint on the hotel's official website. After repeated communication with Ctrip, the hotel agreed to refund the money, saying it was a "communication misunderstanding". I suggest that compatriots should check their credit card information more often when they go out, and safeguard their legal rights and interests in a timely and resolute manner, so that the chickens and dogs of T can't hide.
