Hampton Inn Beaufort

We checked in and went to our room turned the air on and went sightseeing we came back a few hours later and the air conditioning was not working, I went to the front desk and told the front desk clerk and her response was “sorry there is no one here to fix it and I don’t have another room to put you in” so I called the Hampton in Savannah to see about transferring our reservation and she said that was no problem and she didn’t have anything but to hold and she would see what she could do, she came back on the line and said she booked us at the Hilton Garden in Hilton head, she stated all we had to do was go and check in and pay the $80!difference since we had already paid $575... so we pack up and drive an hour to Hilton head and we get there and the front desk clerk says the total will be $655, I explained we already paid $575 and we were told to pay the difference, he said it doesn’t work that way, and that we would have to pay $655 and $575 would be refunded in 5-7 days... So we went back to Beaufort and stayed in a room with no air conditioning for the night and it was fixed the next day, we were given a discount and we decided to check out a day early, so we paid the bill in full and halfway home I check the bank account and we were charged an additional $417, so I called the hotel and they said it was an accident and it would be refunded in 5-7 days... I have always stayed at Hilton hotels and this is by far the worst experience I have ever had... Never ever again
