What should I do if the hotel rent is wrong?

Find the front desk. If the front desk refuses, go directly to the manager. There are vouchers, bills and evidence, which can be taken back. If the other party doesn't admit it, then you can appeal. Write the ins and outs of the accounts clearly, prepare all relevant information and communicate with each other. If the other party is unwilling to cooperate or even refuses to admit the wrong figures in the accounts, then it is entirely possible to bring a lawsuit to the court. Bring a lawsuit through the court to recover your losses, safeguard your rights and interests, and get back your losses. You can ask for a refund. Please consult with the hotel. Your WeChat transfer records are all vouchers. If he doesn't want to give it back to you, you can go through other channels.
