KLM service is shocking. They have no idea what they are doing. Book with another airline.

No one know's what's happened to my flight reservation. The call centre has sent me to the airport twice where no one was of assistance (the worst service). I have paid to reschedule my flight and the call centre agent is telling me something about cancelled flights. I've emailed AirFrance and the response I got was to call the call centre which has not been helpful at all.
