Hanting Hotel(South of Railway Station You'anmen B

I booked through Expedia, got a confirmation, and paid the full $91.85 for one night. After flying to Beijing and taking a taxi, I found the hotel full of cement sacks. The receptionist told me renovations meant I couldn't stay. Neither the hotel nor Expedia had warned me or asked me to cancel, and she said I could cancel the reservation later. When I requested a refund through Expedia, they said the hotel management had refused. Expedia offered me a $25 inconvenience voucher instead. Where did I go wrong? Was that fair? I planned to leave bad reviews for both the hotel and Expedia, but I also wanted to know what I should have done differently so this wouldn't happen again. Expedia's email said they had contacted Hanting Hotel(south of Railway Station You'anmen several times to ask for an exception, but couldn't get the property manager to waive the cancellation fee. They said the booking rules still applied and a refund wasn't possible, then offered USD 25.00 in OneKeyCash for the inconvenience. They apologized and said they had tried to advocate for me but couldn't do more because of the property's refund policy. UPDATE: After two weeks of emails back and forth with Expedia, they refunded all my money, so the issue is resolved. Still, please don't stay at Hanting Hotel You'anmen Beijing.
