Charged Even Though I Did Not Stay
Two things: First, I love the Sofitel Water Tower. One of my favorite hotels in Chicago and my favorite Sofitel among the many I stay at.
Second, I'm really pissed at them right now. I booked a night at the Sofitel for business, but had to do it through the website instead of through our travel department. I then got sent to Omaha for work instead of Chicago. Okay, called the Sofitel and they said I couldn't cancel through them because of the type of reservation I made, but had to do it through their financial person (Sedrick?) and he was not available until Monday. As a loyal a-club/accor member, even the person at reservations understood that maybe they could make some accomdations (change the reservation date?) rather than charge me when they knew I could not make it. 
Called Sedrick on Monday, left a message, and no return call. Called reservations, sorry, need to talk to Sedrick, we can't help you. Now, five days later I get a survey for the room I did not stay in and that they knew I had been trying to cancel prior to my scheduled stay. If Sofitel doesn't make this right, I'm not staying at that location again. While I love the hotel, there are other hotels in Chicago.
