We were at the Hilton Garden Inn Midtown Oklahoma City from 5-7 January. At 8am Sunday, 7 January we received a call on our room phone from an individual claiming to be the hotel general manager. We were told the hotel computer system went ‘down’ overnight and the technicians were unable to fix the problem. The caller then said a majority of the room reservations were deleted and our room was showing unoccupied. To fix the problem he said we needed to “link” our room back to our credit card, but our card would not be charged. Since we were getting ready to check out he was told we would take care of it at the front desk. The caller persisted and said that we could take care of it without leaving the room. Once again he was told we would clear it up at the front desk. The caller hung up before we could finish any more conversation. We called the front desk and asked if the hotel had indeed experienced a computer problem overnight. The front desk clerk stated there was no problem. On check out we gave him a brief explanation of what happened and suggested that other guests may have gotten the same call. I am also trying to contact the specific hotel general manager to relay our experience to him as well. No credit card info was given out due to this contact.
