Horrible. I called immediately after booking a flight because the confirmation email revealed that it was for a one-way ticket and not a round trip like I had intended. I was connected to a representative named Kaladgi and asked her to cancel the ticket I had just purchased no more than 5 minutes ago so that I could rebook a round-trip flight. She refused multiple times, parroting only that it was their policy not to offer refunds and that there was nothing she could do. When I asked to speak to a manager she said that no one was available to speak to me. When I asked for her supervisor’s name, she refused to provide it, but said that someone would call me back in the next 2 hours. No one ever called. I had both my cell and house phone with me the entire day. Now I'm forced to contact my credit card company and have them dispute this charge in order to get a refund. Absolutely the worst customer service I’ve ever experienced.
