Sunexpress Adana-Antalya-Paris Flight Cancellation and Poor Customer Service

I purchased a ticket from Sunexpress for a flight from Adana to Paris with a layover in Antalya. When Adana Airport was closed, I checked my ticket and saw a warning that I needed to contact customer service. Despite not receiving any message or notification from Sunexpress, I reached out and learned that my ticket had been canceled. I contacted customer service 4-5 times to find out if my ticket would be transferred to the newly opened Cukurova Airport, but the company's coordination was so poor that each representative gave me different information. The options they offered were either a refund or to pay the current price difference for a new ticket. It is extremely unfair to ask the customer to pay the price difference for a new ticket when the change is entirely due to Sunexpress. They dismiss this as company policy and do not offer any solutions, leaving their customers in a difficult situation. While other airlines transferred tickets to the new Cukurova Airport without any issues, Sunexpress left my ticket status in limbo for a week, did not provide clear information about the transfer process, and finally canceled the ticket 5 days before the flight, forcing me to get a refund. Because they delayed the process, I had to buy a last-minute ticket from another company at a much higher price. They also deducted a ₺1000 penalty from the refund. Despite their unfair practices throughout this process, they have no respect for their customers, their process tracking is terrible, and I will never do business with this company again. I will take legal action.
