They would not let me board even though I was 45 mins prior to my flight. They said I was too late and provided no refund. Worse customer service experience ever.

Likes: price Dislikes: Courteousness, Integrity, Safety (gate agent gave my seat away then blamed me, the security door was closed. She stated that I checked in too late although I had a boarding pass and lied that there were no more seats. Fortunately, an older gate agent was present and took action to print a ticket for me and they reopened the security door. Then they rushed me to get my stuff as I tried to meet the demand. It is clear to me that was indeed happened is that they already calculated the weight as there were additional seats. The problem was resolved and I had an enjoyable flight, but not without unneeded stress.).

They had no mercy for two women over 80 years old, they only gave them a wheelchair and left them on a waiting list for more than 6 hours, they did not speak English and could not eat or move, they also transported them all the time through the airport from one gate to another. airline customer service are very rude and very abrupt to speak and give information. the truth is I have a very bad concept about the airline
