I stayed at home for one day and two nights, paid a deposit of 600 by swiping my credit card, and spent 374 when I checked out. The remaining 226 said they would return the card, but they didn't receive it for three days. This is normal. At first, I swiped your pre-authorization 600. Just to be clear, I froze your card 600. I swiped 374 from your 600 miles when I left, and the rest will be thawed back to your card later. Just not so fast, don't worry, no problem. If you are not in a hurry, the customer service who sent you the card will say the same thing! I hope my answer is helpful to you and can be adopted. Thank you.
