Can someone who has completed the order guide me? They didn't give us any receipts, didn't count the money or check the car, and just shouted at us to hand in the keys and leave ?

I return the car in the same way, and half a month later, it will be directly deducted from the bank card.

When you pick up the car, the receipt is the billing details. The car rental company should have kept a deposit. If there are no traffic violations during the rental period, the deposit will be refunded to you. If there are fines, they will be deducted from the authorized amount. Your car fee has already been paid. Other fees have been charged when you picked up the car and a pre-authorization was left. If you do not have any traffic violation records later, it will be over. Just pay attention to the bill within 30 days.
