Priceline Priceline.com overcharged Internet

Myself and my wife used priceline to book a hotel in Scottsdale, Az. We stayed at the hotel for one night. Upon checking in the lady at the counter told me that they did not have the room we requested and that for only $50.00 we could get a cheaper room. I asked the lady a few times if it was an upgrade and she told me no it is what they are charging for this room. Once we left the hotel and returned home I noticed in my bank account that we had been charged not only through priceline but also through the hotel. I called and spoke with a few people at priceline and had told them that the hotel room was only $50.00. They said that they would speak with the hotel and let us know what is going on. The next day I got an e mail from priceline telling me that the charges were correct and they were not going to refund anything, even though it was their error. So now we are stuck with a bill for something that we did not approve. I have contaced the BBB and they are taking care of the issue and are trying to get our money back from priceline. Do not use priceline, they are a scam.
