Today I made a reservation through Expedia for a hotel in Ireland. I arranged to pay at the hotel. After I made the booking I received a notification from guest reservations that I had secured the best room rate at the hotel, but I needed to complete a form requesting information including details of my credit card. I then found that my credit card had been debited over 1,000AUD. I have no idea why. I contacted NAB who advised me to contact Expedia but Expedia said it was my fault. I have contacted Guest Reservations but have not heard back yet. My experience so far suggests that Guest Reservations is an organisation that is just out to scam people. My advice is: DO NOT USE GUEST RESERVATIONS UNDER ANY CIRCUMSTANCES.I have now received a response and also a full refund from Guest Reservations. Although I am pleased with the refund, I can tell you that their email reply to me is misleading.What they did to me is what they do to all people. I think I was charged about $30 (AUD) by guest reservations, for a service I did not receive. Therefore, my message to all remains:DO NOT USE GUEST RESERVATIONS UNDER ANY CIRCUMSTANCES.
