Hotel Laudinella

Hello Expedia, This is regarding Itinerary # 72527315933031. We booked two rooms for two days at Hotel Laudinella in St.Moritz, Switzerland from 10 to 12 June. I initially contacted you on 4th June regarding cancellation of one room, explaining the situation of my parents, who are senior citizens and were tired after sightseeing and travel in the US and were unable to travel to Switzerland. Expedia spoke to the Hotel and informed me that the hotel is not accepting cancellation. Then I called the hotel directly and the lady initially said that I can speak to the manager once I am there at the Hotel on 10 June. When I reached the Hotel on 10th, I explained the previous discussion had with Expedia and the hotel staff and I told him that we are only two adults with one child and we need only one room. He did not entertain the request and gave me the keys for two rooms. He said that he cannot do anything and the people in the reservation desk already left for the day and I will have to wait till next morning. Next morning, I enquired for the reservation desk, but the lady at the reception called a number and asked me to talk to the person on phone line, saying that the other person on the line is from the reservation team. The lady on the phone line rejected my request citing Expedia rules do not permit to refund/credit. So, Expedia is blaming the hotel and hotel is blaming Expedia. I request you to look into the problem and issue a credit so that I can use it later.
