NO clear information causes loss of money

<p>I missed my flight by 10mins and at the boarding gate the two assistants said they are unable to help me as I was taken off the system. I asked them what can I do? They said my ticket can be changed for a later date. I asked them if there is another flight to PE and they indicated it's the last one. I asked about the route to EL and they directed me to other airlines. I asked if it's possible to speak to a supervisor, they said no. I then left in a hurry to see if they I can, which I did with an alternative airline. As I land at PE airport to try change my ticket, I am told that it shows that I have flown, which I did not. The lady then explains that I had to change it within two hours, which had already passed and means I forfeited my money. How is this possible as I was never given the correct information to start with. They two assistants knew that I needed to fly the very same day, they could have had given me all the necessary information as I was the only client they had to deal with so that I make the correct deionised. But they didn't, it's such a poor, no worst service I have ever encountered. How possible is it that when a client wants to speak to a supervisor and they are not directed to one. Why is it that its only that one can make changes within two hours? It is unrealistic as if one has missed their flight, they can always book an alternative one with another airline. My company uses this airline for business and will ensure that it never does in future.</p>
