SunExpress Airlines Extra Credit Card Charges After Months

SunExpress Airlines charged ₺194 to my credit card, and when I called them, they said there had been some mistakes in the past and that certain charges from previous flights hadn’t been collected, so they charged them again after about a year. Okay, but at least you should have informed your customers, right? I thought my card had been hacked and was about to block it! Why aren’t you notifying your clients in advance?
