Don't use booking.com

I made a reservation at Hotel Cervantino using booking.com. When I arrived at the hotel, the receptionist had my reservation but claimed there was no record of my payment. The hotel also claimed that their credit card machine was not working. They required that I pay in cash. Since I had just arrived in Mexico, I did not have enough pesos with me. They sent me out on foot to find an atm machine. Once I paid for the room in cash and got to my room, I found the hotel had already charged my debit card. When I reported the problem to booking.com, t hey required my bank statement and copies of my receipts from the hotel before they would even make a call to the hotel to resolve the issue.This level of customer service is unacceptable. I will never use booking.com again.
