I bought - airline tickets using credit card .but after three days get emergency ca n't fly on the dates .so I call credit card and did disputes. After few days they send me letter in mail explain to me about dispute. That 's was give me - credits for - airplanes tickets and they will process the dispute. I call that credit card to let them known l do n't want to loss that money if you ca n't getting the money so I could Chang that date for the tickets with airline but credit card company told me it 's no proces and we credit your account and that 's finally, l said that letter do n't say she said discard that letter. Month later get changed on my statement for that - tickets and send me a letter telling me we ca n't get your money back. So I call the credit card but their answer was we are very sorry
