Dear sir,
I am one of the customers of your flight company. Through this letter I would like to tell you something. This is about the services of your company.
Last Monday, I flew to Medan on the flight number GA 116, on the schedule board, it is stated that the plane would depart at 07.00 am. But fact I had to wait for an hour before taking off. It has happened many times, because of that I was late to attend an important meeting at my office in Medan.
