<prompt> Human: Hey everyone! Im new here but I know that you guys typically have some really good advice on how to deal with tough situations, hopefully with your help I can get this mishap straightened out.Late last month I was attempting to purchase some airline tickets through Expeida.com learned my lesson and after the purchase I noticed that the flight out to my destination was not booked. The itenerary said that the booking had failed and that I would be contacted to resolve the issue, but my return flight was booked and paid for. I looked at my bank account and noticed that only the return flight had been charged and there was no indication of an out bound flight. After calling Expedia, they never called me, I was told that they could not confirm my booking with Spirit Airlines never again and that I would have to call them to figure it out. After a long, long round of robo-tellers I was told by Spirit that they could not sell me the tickets at the quoted 311, instead it would cost 542... I told them Id find a different flight because that is absurd.Since I already had a return flight, I immediately purchased tickets to my destination also through Spirit to avoid raising ticket costs. Everything looked fine, the tickets cost me 60 more than I had originally expected but I was at least booked. Fast forward to yesterday when I decide to look at my bank statement. As I look down the list of charges I notice that there is a 380 charge from Spirit on the day I booked the second set of tickets AND a 542 charge from the original Expedia tickets originally quoted at 311. My first course of action was to call Spirit and try to dispute this with them, they will not refund the full cost and cancelling is going to cost upwards of 175. Expedia was my next phone call and they state that its not their fault because they cannot guarantee prices or tickets but they somehow can invoice me for a specific price.At this point Im not really sure what to do... I booked the flights using a debit card and Im not sure if my bank canwill help me get this money back. The flights arent until December 23rd, so I still can cancel the flights through Spirit but I feel like I shouldnt have to pay a cancellation fee when I never authorized the 542 tickets...Im open to any advice and Im confident that you all will be able to point me in the right direction. Being that its Christmas time, this is causing me a lot of extra stress since I have presents to buy and things to plan for. Thanks!tl;dr- Expedia quoted me less for a ticket than Spirit was willing to sell for, I declined and booked another flight, Spirit still charged me for the original ticket.Assistant: File a chargeback with the bank, quoting the services actually received and their cost.Never ever use a debit card at Point of Sale. Use a credit card instead.Human: Is there a possibility that I will lose the dispute? Im worried that the chargeback process will take too long and I will have not be able to cancel the flight if my bank says they cant help.It was a huge mistake using a debit card in this situation...Assistant: It will work out just keep pounding the pavement.In the future, just use Google flights instead of travel aggregators. Additionally, discount airlines rarely end up being cheaper.Human: I tried to use Google flights, but it wouldnt go through for this ticket... probably due to exactly what Im dealing with now. It seems like Spirit was advertising one rate through these sites but charging much higher to get the actual ticket. It is actually a pretty smart, albeit shady, little scheme they have going on... Get one of your tickets for advertised price and then jack up the price on the other leg of your journey...  <response>: Yea Ive always just paid the premium to go with full service airlines. Theyre a mess to deal with but at least only due to incompetence and not by design
