Atrium Hotel & Suites Charged my credit card after I cancelled a reservation. Dallas was iced over last weekend. I could not travel. Irving Texas

I registered for a real estate seminar at the hotel last weekend for friday and saturday night--this was done about two weeks in advance.  Incliment weather shut down the interstate in my city and many roads and destinations for Dallas and Irving.  I called the hotel to cancel the reservation.  They charged my credit card anyway.  When I called the hotel they were very rude and I could tell it was a lost cause.  I am contacting my bank to file a charge for unauthorized use.  This is supposed to be a reputable hotel and any management that wants to charge a client for incliment weather should not be in business especially since I called.  I am contacting the Attorney General as well as an hotel associations I can find.  I am also asking my network to report this on the social media outlets they have.  I think it is a sad state of affairs for this company.
