I'm writing to complain about the poor customer service you've given me and my family. I calles your airline to change our flights to indonesia - there was an emergency there and i was advised to delay my visit. I e-mailed you several times and calles your seevice desk, but got no answers. In the end, i had to go to the airport to change the floght - the journey cost me $40. I booked new flights for two months' time, and was amazed when you made me pay a $300 penalty for the new booking. You said the new booking had to be within 14 days of the earlier booking. I'm disgusted with the way you've treated me and my family. What are you going to do about it?
