Hotels with Breakfast in Cordovilla

I made a booking for the San Fermin festival through their website for 3 rooms (we are a group of friends going together). One main reason we chose this hotel is because they only required a credit card in case of no-show, and the reservation said payment would be collected at the time of check in (July 7). Well, weeks after the reservation, without warning, they charged my bank account nearly $2000 US and said that's their policy for the festival (but nothing was indicated on their website). In fact, this is what my confirmation email says: CREDIT CARD DETAILS Your credit card won't be charged this amount (payment is to be made directly at the hotel on the day of arrival), unless you have booked a non-refundable rate or if stated otherwise in your rate's terms and conditions. In the event of a no-show, you will be charged a certain amount depending on your selected rate's cancellation policy. They refused to honor the terms of the reservation and caused my account to go into insufficient funds. Luckily, we were able to cancel and book at a different hotel. Horrible bad impression to leave on a guest. I get that you're expecting a full house but you cant change the terms that were agreed upon just because you feel like it.
