Very disappointing and frustrating

Disliked: Using Booking.com to make the nonrefundable reservation, the date automatically entered was for next Friday versus this past Friday. After trying at length to change it with Booking.com, it was successfully changed and I received an email confirming the hotel had the updated reservation. The employee at the hotel said it wasn't in her system. I called Hilton Customer Service. After being on hold for almost 15 minutes, I was told they couldn't help and to contact Booking.com. After 3 hours, I checked again with the receptionist at the hotel and she said a manager told her to accept the reservation. We were there in person yet the receptionist didn't bother to let us know that we would be able to have a room. Given the amount of time that had expired, the hotel no longer had a room available as requested. There was also no room service. While the situation was caused by my error, It was a stressful experience with very poor customer service and a "too bad for you" attitude. It was my first and last visit to this property and to other Hilton properties. There are many other options where hopefully, customers are valued.
