How to complain about the cancellation of hotel reservations and credit card deduction in the United States?

First of all, I suggest you check the cancellation terms of American hotels, whether there is a cancellation time or whether the cancellation fee is not refundable. Many hotel reservations in the United States need to be cancelled x days in advance. If they don't cancel according to this agreement, the hotel has the right to deduct the room charge, usually one day. If there is no such agreement or you have cancelled the contract according to the agreed terms, you can apply for a refund directly from the hotel.

Then you can contact the credit card customer service hotline and ask the issuing bank to initiate visa refusal, which will take a long time.
