Getaroom  - Billed for cancellation plus tax recovery and cleaning charges

We made reservations via toll-free number on March 19, 2022 at the Tru by Hilton Hotel in Oxford Mississippi. The reservations were for June 23-27, so approximately 60 days prior to arrival. Within hours we realized that the dates for our trip had to be changed so we called to cancel our reservations. At no time in either phone call was there any mention of there being a non-refundable policy. We thought we were dealing directly with Hilton! Were we surprised to discover that we had been billed $716.00 on our credit card! We tried to call hotelvalues (who sent us notice of cancellation and billing) to no success — no phone nor website. But I did notice complaints against Getaroom.com and traced them as being the company who made the reservations. After failed attempts at calling Getaroom, we contacted our credit card company and filed a dispute. Just heard back from Capital One who said no cancellation policy was on Getaroom's website therefore there was nothing they could do. But this policy was not stated in two phone calls! How were we to know? I should also mention that we are held liable for $216 of tax recovery & service fees which are the estimated amount "we pay the hotel for occupancy related taxes owed by the hotel and any amount charged to us for resort fees, cleaning fees, and other fees." How can we be charged occupancy and cleaning fees when we're not in the room? Getaroom.com or hotelvalues.com is a SCAM!
