EDREAMS DEDUCTING MONTHY WITHOUT AUTORISATION

I bought a flight ticket in October. I never signed up for any subscription nor did I give any authorisation for Edreams to deduct from my account every month. They are using my card details I used to pay the flight ticket, this is ******* and unetical. I can't stop it with my bank as they are using my card details. I am now struggling to get answers and a refund from edreams. Edreams are ****** & using clients personal information, confidential information for their own company use and gain. I don't recommend anyone to make use of their services and be cautious giving your card details to them. I am very dissapointed and I have lost money for the past 3 months that Edreams have been unauthorised deducting from my account.
