Charming Cotswold Cottage in a private setting

They cancelled on me. Said they would refund me, but because of currency exchange rates, I lost money. I messaged them multiple times about it and never received a response. Their reason for cancelling was that it was Christmas and a 3-night minimum was required, where I was booked for only 2. It was AFTER Christmas-not over/during, nothing was stated about a minimum, and it let me book the stay. By the time I was informed they were cancelling me it was too late to get another equal place nor did they allow me to just stay an extra night. I do not feel as if I needed to pay the difference given all of these factors. And, again, they never replied to any of my communication.
