<prompt> Human: Hi, so im a student, living 400 miles away for university. I fly back and forth all the time and have probably spent the guts of 3000 with this airline over the last three years. Recently, I was on the site and was trying to change my seat, I accidentally clicked the change my flight button and my flight was changed from the 1st December to 24th November. The airline charged me 143 for this! So, I rang up and asked for it to be changed back to the 1st and to get the money back, the customer service worker over the phone did return the flight back to its initial date and time but she refused to give the money back.So, I rang up again and got no further forward.I am a student and I need this money, I am saving up for a holiday for California and I had to take money out of that savings fund in order to replace the 143. I understand that what I did, does require me to pay, but at the same time, I reported the incident to the airline within less than 5 minutes after it occurred and I changed my flight back to the original one, so in essence, I didnt really do anything differently to the original booking and they are taking my money for nothing. You know, I havent changed my flight to a different hour or date, it is the same date and time as it was before all of this happened.I emailed my bank last night, requesting that they stop this transaction but they didnt do anything and the money is gone now. I really need this money back. Is there anything that I can do to get it back? Even the fare difference would suffice, just to get some of it back as it was a simple mistake and I dont think that it is fair that they have taken this amount of money when nothing has been done to the reservation. Assistant: Im sorry to hear this but how could you change the date of the flight and go through all it requires to finalize it without realizing you are doing something wrong.It sucks, but I think the money is gone and you should see the money spent on a lesson to be more careful. See it on the positive side, it could have been something way more expensive. Human: Because of the way the website was set up, it was easy to do that on their website. So, cant I even get the change fee back? They essentially have my money for nothing. I am going to send them a large letter requesting it back with supporting evidence. Assistant: It isnt nothing. They changed your flight for you twice at your request.Human: Yes, but it was returned back to the initial date, and I rang up immediately after I made the mistake.  <response>: Yes, but that was your mistake, not theirs. Theyre not responsible for your mistake.
