We are members of Accor (All.com). We were driving through France, and decided to stop for a rest and continue the next day. We selected the Ibis Chalon-Sur Saone Europe Hotel, for its proximity, in addition to knowing it, since we stop at it at least twice every year. When finalizing the reservation through the app, we realized that the dates were wrong, so we immediately canceled and made the correct reservation. Upon arrival at the hotel we were assured that the refund would be made within a few days. A month later, it had not happened. We called the hotel, and they asked us to send an email. It's been another 15 days since we sent the email, and they haven't even responded. I called today, and the employee told me that the hotel's policy is not to return reservations made and paid for through the application, if they are canceled. I asked that person what the advantage is of being a member and booking through the application, and he replied that "he wouldn't know how to give me an answer", but that he should call tomorrow to speak to someone else or send an email (one of those that they don't answer). Conclusion: do not make the reservation through the app. Do not pay your reservation in advance. Book by phone, and pay at the hotel when you check out.
