瑞吉飯店(The St. Regis Hotel)

We have a bad experience with St. Regis. We told the front desk to help us to book a big taxi for 4 people to take us to airport in early morning, but the staff didn't mark it properly, when we double checked the 2nd time, the order wasn't there and turned out a small taxi came and they needed to reorder a big one for us. They mixed up the room charge, it was remarked to pay at the hotel, first time the staff gave us the wrong info that both rooms were already charged to my card. Then the next day, they said it was not charged yet, we told them we paid by different credit cards, but when we checked out, they charged both rooms on my card without my permission. Finally, they cancelled 1 room payment and charge it back to my friend's card. This is very unprofessional and I haven't received my statement yet and not sure if they really cancelled the wrong payment.
