eDreams Charged My Credit Card Without Authorization After Booking Family Flights

I recently used my credit card to book flights for my brother and his family through eDreams, and at first, everything appeared to be in order. Today, I took a look at my account and discovered an unexpected charge on my card that I neither authorized nor was aware of. I did not authorize eDreams to apply extra charges, and this unexpected transaction has raised my concerns regarding the safety of my information. I anticipate that eDreams will honor customer consent before making any deductions and will promptly address this issue. I seek confirmation that this unauthorized charge will be refunded quickly, and I would value steps taken to avoid such issues moving forward.
