getaroom.com fraudulent charges on my credit card internet

On September 18, 2013, I tried to book a room in Days Inn Las Vegas through getaroom.com. I registered and provided my information including the length of stay from Set. 26 - 29 2013. It charges me a total of $142.98 for the duration of the stay. I entered my credit card information, but when I hit submit, I received an error message and to try again later. So i tried again for two more times. I received the same error message. 

On September 19, 2013, I logged to my online banking to find 3 pending charges of $142.98. So I contacted getaroom.com. In my first call, the lady was very helpful. She made a request to release hold on my funds to my bank. I was told to give a couple of hours to see the reverse online. Well, six hours later, it only reversed $142.98. So I made a phone call to getaroom.com to ask for an explanation why the 2 pending charges of $142.98 are not beibg reversed yet. This time, the lady that was helping me was rude. Her name was Shan. She thinks that I should be grateful that she was helping me. After the unauthorized charges, I should be thankful that this thief is helping me so I get my money back from them? I know she did not do it personally, but at least show some effort and don't get the idea that you are better because you are trying to help me. The employees in getaroom.com should understand that they owe to the customers all the effort to resolve the issue. Just return the money! or better yet. Getaroom.com, stop charging credit cards without authorization. It is called stealing and bad business practice.
