Kimpton Hotel Monaco Denver, an IHG Hotel

I will never book with Kimpton hotels again! In April, I booked a room and ended up having to cancel it. I cancelled the reservation twice (as they didn't cancel it the first time), once by phone and once online, a month in advance. After my reservation date passed, they charged me for the room, despite sending me a cancellation code via email. When I called the corporate customer care number to dispute the charge, I was told that the cancellation code didn't show up in their system and suggested that I call the front desk at the hotel in Denver. At present I am still waiting for my refund but overall, it was very disappointing customer service on a corporate level. It is ridiculous that it should be this hard to cancel a reservation. I should add that the accounting staff in Denver were pleasant and helpful, however.
