First off, I thought I was on the hotel website booking my stay but apparently Hotelsone came in through the backdoor and took the booking. Anyway, they got my dates and amount of rooms completely wrong. When I tried to call their customer service line they ask for my phone #, itinerary #, or last 4 of the card used on the purchase for reference. They never sent me a confirmation email do I had no itinerary number. They said they did not recognize my phone # or card # in any recent booking yet they CLEARLY have my card # because they CLEARLY, immediately charged my card! I could NOT get my money back and had to call the hotel to book with them paying DOUBLE for my stay!
