Upon arrival at the hotel, which we had booked via Hotels.com, we were informed that the Hotel was undergoing renovation and not available for us.
We were offered another, cheaper (in both terms of the word), hotel, and that we could let the original reservation stay as-is on hotels.com
We politely informed them that while we could stay at the other hotel, we would like to cancel the original reservation and pay directly to the other hotel, as it was cheaper and of a lower standard (no exterior windows, for instance).
Upon returning home we find that they have refused to return our money
