I stayed at your hotel in Rennes during 2nd January - 8th January 2017.
My room was payed in full using Hotels.com by my company travel department.
Nevertheless the hotel charged my credit card for 397.48$ without any further explanation.
I've sent several emails during last two month to hotel receptionist, Lucie. She confirmed mistake, but didn't helped, asking me to contact contact another travel agency, completely unrelated to the case.
I still didn't get my money back.
