AccorHotels review: Overpayment

My wife and I stopped at the Ibis, Deauville, on the 22nd/23rd September 2023 which we booked through Hotels.com. My wife booked the stay, using her debit card, on the basis that the bill would be paid in full, at the end of our stay, which it was. Unfortunately, the sum of £105.00 was taken by you from my wife’s account using her debit card, on the 15th September. This was obviously prior to the stay. When we left the hotel, I paid with my credit card (different to the one initially given to Hotels.com). We have stayed at your hotels for a number of yours, and used the same arrangement of booking with one card and paying with another, and never had an issue.

I sent an email on the 15th October, to what I understood was the address of the hotel, asking for a refund of the £105.00. This was after numerous attempts to contact Hotels.com. To date I have received no acknowledgement or reply to this message.

Could you please investigate and let me know, what the situation is with this, as it is not an inconsiderable amount.
