The error occurred when I was adjusting… The error occurred when I was adjusting our flights to fit within my daughter's school schedule. Without realizing it, I accidentally changed the return date instead of the departure date—an innocent mistake. Upon noticing, I contacted Trip.com immediately. They offered to change the tickets but couldn't confirm the payment amount at the time, promising to inform me if the change was successful. While waiting for their feedback, I contacted KLM directly. They confirmed that plenty of seats were available on the flight I wanted, but since I had booked through Trip.com, KLM was unable to assist and advised me to request the changes through Trip.com. Later that day, I received an email from Trip.com saying the change had been declining, and I was instructed to use their online portal to book another date. When I did, the only options available were either two business class tickets for the day we had initially planned to fly—where they would cancel our original tickets, meaning we would forfeit the entire amount already paid and would have to rebook at the full business class rate—or paying an additional €2500 to secure a ticket on another day, cutting our trip short by two days. Ultimately, we ended up having to pay €10,000 for the return tickets to South Africa because of the way this company conducts its business. Their behavior is nothing short of predatory, exploiting innocent mistakes and leaving customers with outrageous costs or ruined travel plans. Despite seats being available, they refused to provide a reasonable solution, trapping us into these exorbitant fees. Please be careful and use any other travel agency—this one is honestly shocking.
