Turkish Airlines Flight Delay and Transportation Issue

I purchased a ticket for THY flight TK 7541 from Antalya to Sabiha Gokcen scheduled for 23:05. I received an SMS from THY stating a 35-minute delay. Upon arriving at the airport, I was informed that the flight would depart at 23:50. At 23:50, THY officials verbally informed us that the flight would land at Istanbul Airport instead of Sabiha Gokcen. They assured us that we would be transported to Sabiha Gokcen for free. I explained to the officials that my car was at Sabiha Gokcen and my home was in Cengelkoy, meaning I would have to travel back to Sabiha Gokcen to retrieve my car and then drive home. I requested to be dropped off at Levent or Kavacik at the very least, but was told that the vehicles would go directly to Sabiha Gokcen without stopping. I had to take Havaist to Levent and then a taxi to my home, and I will need to take time off work tomorrow to retrieve my car from Sabiha Gokcen. Despite having a ticket for the 23:05 flight, I didn't get home until 03:30. I am deeply disappointed with THY, which claims to be the world's best airline. It's truly unfair to treat people this way.
