When Can't You Get Help When You Have A Problem With The Price O

we booked two nights at a price ,then after we booked the room and paid for it,we found out someone had got our credit card number so the bank sent us a new one. I called to give the motel the new number right when I received it. I was informed that the room was canceled so I booked them again but they will not reduce it at the price I had got in the first place! I tryed to get a hold of someone and after three hours I finally got a hold of a person and when I asked this person questions they hung up on me! I have booked through hotels.com for years and never had a proublem till now
